Part of the issue in the past was that a lot of the wrecks that were salvaged had casualties. People weren't happy when they found out that unscrupulous individuals were robbing war graves. Ships that sunk without casualties are easier to accept people cutting up for profit.
@VaderxG This is like saying it's ok to take headstones from a graveyard cause they're just rocks. The ships aren't simply the place these people died but also their final resting place. HMS Repulse and HMS Prince of Wales sank with almost all hands but have been completely destroyed by salvagers. The UK has said these ships are not to be disturbed but the wrecks aren't in international water and the local government just doesn't care. The only reason similar things didn't happen to USS Arizona and HMS Hood is because Hood is too deep and the US decided Arizona wasn't worth the trouble to raise until after the war at which point public opinion wanted a memorial to Pearl Harbor.
@@Ebolson1019 the line between archeology and grave robbing is a fine one, but certainly anything that sank after 1850 is definitely off limits for explotation if its also a grave. (Most sunken ships are also graves) Your best argument to touch them would be an environmental one of wanting to remove it from the water and place it in a museum of some kind. (And make a memorial/tomb for the deceased) But the argument of "economic benefits for an individual" is definitely just grave robbing with extra steps.
I didn't think there was a need for low background steel anymore because there are new processes in place during the manufacture of new steel that basically eliminates the existence of radioactive material.

@@cymond It's getting pretty annoying to be honest. I clicked this already with an understanding of the topic, but was hoping I'd learn more from it, instead of wasting six minutes listening to bad jokes.
If you were to melt this pre-1945 steel using oxygen to melt and reuse it, aren't you still incorporating Co-60 or other radioactive elements into the steel?
In the Philippines, illegal salvage of famous WWII shipwrecks is a problem for this reason. These shipwrecks are considered war graves, and of national importance to their country of origin. The UK conducted an operation to retrieve the bell of the HMS Prince of Wales, which was involved in the sinking of the Bismarck. They knew the ship was being illegally salvaged, and wished to save the bell. There are reports of piles of human bones littering the shore where they break down and process the metal.
Interestingly, the Wikipedia article on low-background steel mentions old railroad rolling stock as another source. Makes me wonder about pre-ww2 cars, is the metal too thin or are they simply worth more intact.
Most likely neither. All pre ww2 cars have either already been scrapped and melted down for parts, or are sitting in a land fill under 80 years worth of garbage, making them not worth digging out.
@@Tommy50377 so basically any pre ww2 car that is actually accessible is definitely worth more as a collector's item than as scrap steel for use as low background steel. Especially considering the dropping demand for specialty pre ww2 steel as background atmospheric radiation is dropping to more "normal" levels.

The story of the Germans scuttling their own Navy in a British port after surrendering so that the British wouldnt get their ships is a really interesting story but it gets completely swamped by the all the snarkiness in this video. May I suggest a video on this topic in the future?
And it's important in this qestion as it was a planned scuttling after hostilities had defacto ended. So no-one went down with those ships and thus they are not classified as sailors' graves. So they can be legaly salvaged.
The British actually were quite happy they scuttled it. The alternative was that the ships got split up around the allies. The Royal navy was already far ahead in naval size, so they could only lose from the German grand fleet being given to others.

@@schwig44 You can, and that's usually what's done. Now, I'm no professional, but my guess is that subtracting the average background count rate isn't good enough if you want to be extremely precise, or if the amount of radiation you're trying to detect is so small that it's impossible to tell apart from natural variation in background radiation.
@@schwig44 Seb135 has it right. Radiation is not a constant thing. Each emission is entirely random, and even if the average emission rate is low, you want to be able to tell that apart from the background. In nuclear facilities, for example, you want the emissions from a person to be at normal, background level. That means not having your detectors swamped by the room's walls. Good operators can tell how many bananas a person has eaten recently - they are naturally radioactive.

Unfortunately, the value of this steel has created a sort of "black market" and illegal salvage ops have disturbed the "final resting place" of sailors. Some wrecks are now missing from the sea floor, their crews remains having disappeared with them. 🙏 RIP
It may be sad that they're removing the graves, but removing the ships from the ocean is actually really good for the environment. Lead in these hulls can cause increased heavy metal in marine organisms, and the iron can make invasive corals take over healthy reefs. So while it sucks that these graves are disturbed, it's overall a good thing that the ships are being removed.
@@aliciacardella9526 with the coral reefs, and thus the marine life that relies on them, being fucked over, don't we kinda need invasive corals in the world?
@VaderxG pretty sure even the skeletons are gone after this long. It's unreal the kind of pointless stuff people decide to get worked up about! Everybody who died in WWI have been dead for 100 years, and even their grandkids are almost certainly dead too. If they have spent 100 years in Heaven now, they certainly aren't going to be upset that someone moved some metal around near where their dead bodies settled 100 years ago. And if they just don't exist, they also won't care.
Before clicking on this, I guessed why pre-1945 steel was prized I also knew about the German fleet scuppered at Scarpa. Bonus fact: To scarper is Cockney rhyming slang. Scarpa Flow - go.
This is wild to think about. I’m a train conductor and each piece of rail they use is dated. I found a piece of rail dated all the way back in 1919 that is still in use today. Crazy to think that rail was made 20 years before any nukes were ever detonated and it’s in use today.
There's still some stadiums standing that are pre 1945. Wrigley. Fenway. Rose Bowl. Michigan Stadium. Franklin Field. They would also have this special steel in places.
Did anyone else notice the subtlety that the steel beams in the left were oriented to be an H and the ones on the right were oriented to be a capital I, as in H(alf) as I(nteresting)
"Why steel- making is sometimes done with pure oxygen in a clean room environment" sounds like an interesting video especially if the details of the process are discussed.
Calling it Scarpa Bay really turns that bit of Cockney rhyming slang on its head. From Scarpa Flow - go, to Scarpa Bay - stay. Anyway, I’m in a rush, I need to Scarpa

I do love me some Helen Mirren. She still a fox too. Also don't tell me that I wouldn't click on a video titled "Why steel-making is sometimes done with pure oxygen in a clean room environment". You don't know me.
Damn. I have like 6000lbs of train track from the late-1800s laying around and I got really excited that I had a payday stacked behind my shed. Then you had to go a kill my brand new dream.
for one of the first times ever I actually know where this one is going (spoilers) Its for geiger counters and other things that need steel that isn't radioactively contaminated
Without watching the video, I'd guess it's because it's missing the trace levels of radioactive content in the modern era when trace levels of radiation make a difference to sensitive equipment. Am I right? Or should I watch the video?
2:30 That hits too close to home, lol. I was trying to date a girl and it came up that she thought 9/11 was an inside job and the steel beams wouldn't melt and stuff. So that clip brought back a now funny memory (not at the time, though)
well she's right, jet fuel doesn't even get close to the temperatures needed to soften steel, the twin towers were actually build with plane attacks in mind and would be able to resist them, the most likely scenario is that thermite bombs were used for which there are indications on footage but we'll never know what really happened excapt for the fact that the planes alone weren't the ones who destroyed the towers and that something else helpt with that
The part you might have mentioned is that the pre-boom steel is so valuable that breakers have been disassembling ships marked as war graves. Most of the ships from Scoppa Bouy had already been recycled.
this was, at the very least, 3/4 as interesting. it reminds me of an incident in Mexico involving radioactive equipment being dismantled at a junkyard by unqualified workers, the "Cobalt-60" incident - there's plenty of information if you're interested.

Not sure how accurate this is. The steel making process shown, blowing air through molten pig iron, is the Bessemer process, which has been displaced by the basic oxygen process. There was also an error claiming that the pig iron had to be melted, when in fact, pig iron was almost always taken directly from the blast furnace in molten form and then blown with air to burn out the carbon. The problem with the Bessemer process is that the nitrogen in the air made the steel brittle. I do not know what process is typically used to obtain the oxygen (cryogenic, pressure swing absorption, etc.) and what the residual carbon dioxide content is.
I was wondering why companies were mercilessly scavenging WW2 shipwrecks (gravesites) in the Pacific. This is why. Astounding that I am mid-40s and never knew this.
Worked in a steel mill for 35 years. It had a state of the art Basic Oxygen Furnace way back in beginning of the 70's. The scrap steel used in the mix was sorted and graded. The company made excellent steel. Problem was the flooding of the markets with offshore Chinese steel, that had all kinds of crap in it but the bottom line always wins and manufacturers bought the foreign steel for cheap and the government only action was to spend years in delayed trade dispute talks that would result in a small fine, but even that windfall did not go to the injured steel industry but into the governments general funds. This is off the ops topic but it is relevant.
Congrats, you successfully talked about steel for a total of 2:28 before the inevitable everyone knew it was coming “Jet Fuel Can’t melt steel beams” joke.
1) It amazes me how useful your Shrek analogies are, especially since I never saw either of those movies and couldn't even make a decent guess about whether or not there was a third. 2) In your defense, the world has never been quite the same since Dame Helen appeared.

And some ships at the bottom. Albeit less than there used to be.
2:28 hornet's nest was kicked subtly, who else noticed? lol
2:24 beams that can't be burned by jet fuel? A nod to "planely difficult"?
Unfortunately, the value of this steel has created a sort of "black market" and illegal salvage ops have disturbed the "final resting place" of sailors. Some wrecks are now missing from the sea floor, their crews remains having disappeared with them. 🙏 RIP
It may be sad that they're removing the graves, but removing the ships from the ocean is actually really good for the environment. Lead in these hulls can cause increased heavy metal in marine organisms, and the iron can make invasive corals take over healthy reefs. So while it sucks that these graves are disturbed, it's overall a good thing that the ships are being removed.
@@aliciacardella9526 with the coral reefs, and thus the marine life that relies on them, being fucked over, don't we kinda need invasive corals in the world?
@VaderxG pretty sure even the skeletons are gone after this long. It's unreal the kind of pointless stuff people decide to get worked up about! Everybody who died in WWI have been dead for 100 years, and even their grandkids are almost certainly dead too. If they have spent 100 years in Heaven now, they certainly aren't going to be upset that someone moved some metal around near where their dead bodies settled 100 years ago. And if they just don't exist, they also won't care.

"How old are you?"
"I'm two Cesium-137 half-lives old"
I know this one. It's the lack of any radiocucleotides after the first nuclear weapons test, needed to various instruments.
3:27 i admire that ONE guy that's running in a different direction. do your own thing, amigo!
Likely a messenger, WWI radios were primitive, bulky and short ranged; frontline messages had to be relayed by runners.
Wondering how many people caught the “beams that can’t be melted by jet fuel”…

@WiZZard for everyone making that joke i would have some loose change
1:55 First bricks, now steel. What's next Half as Interesting, wood?
Before clicking on this, I guessed why pre-1945 steel was prized I also knew about the German fleet scuppered at Scarpa.
Bonus fact: To scarper is Cockney rhyming slang. Scarpa Flow - go.
That pronunciation of Scapa flow physically hurt me
I really enjoy this channel,I know you probably hear this often,but you make the boring stuff very,well, interesting!
Its only boring if your teacher is doing it poorly.
Not only that, but now I can ask the wine steward about the cesium-137 concentration in my wine!@# 😂

This is wild to think about. I’m a train conductor and each piece of rail they use is dated. I found a piece of rail dated all the way back in 1919 that is still in use today. Crazy to think that rail was made 20 years before any nukes were ever detonated and it’s in use today.
There's still some stadiums standing that are pre 1945. Wrigley. Fenway. Rose Bowl. Michigan Stadium. Franklin Field. They would also have this special steel in places.
We have a station roof made out of early 20th century steel. Crazy how long this things can last.
My favorite building material being discussed on HAI, except for, of course, those red hard rectangular things called BRICKS.
Did anyone else notice the subtlety that the steel beams in the left were oriented to be an H and the ones on the right were oriented to be a capital I, as in H(alf) as I(nteresting)
If that was intentional, then that was simultaneously clever and horribly vague
This video was like 50 % jokes and 50% actual information.
"Why steel- making is sometimes done with pure oxygen in a clean room environment" sounds like an interesting video especially if the details of the process are discussed.
I didn't understand what World War I was until I learned that it was like Shrek 1 and not Shrek 2. Thanks, Half as Interesting!
Finally I know how to tell whether a person was born before 1945, really learned something in this video, thank you!
Calling it Scarpa Bay really turns that bit of Cockney rhyming slang on its head. From Scarpa Flow - go, to Scarpa Bay - stay.
Anyway, I’m in a rush, I need to Scarpa
Half as Interesting makes videos on random topics so interesting. Appreciate the hard work. 👍👍👍
👍
Did anyone notice that the steel on the left forms an H and on the right forms and I, Half as Interesting??
3:00 you underestimate the kind of people who watch this channel. Of course we'd click it.
Yo, this made me really appreciate the work being put into proper headlines. Nice sidebar!
Also I thought I was not interested in the Crime Spree series, but it was super fun. Also really loved the Colorado documentary. I can not find the St Helena one though… the search on Nebula is, let’s say not as great as the content on it.
This video has a lot of the same energy I have when I’m making up a lesson plan for a class that starts in 10 minutes. It’s a compliment, I promise
That was weird. In the first sentence of this video, your voice sounded exactly like that weird guy from wendover productions. From then on it was just your normal HAI voice
I thougth for the bad news you were gonna talk about how this demand for low background steal lead to a lot a people disturbing and destroying old shipwrecks which for civilian ships the final resting place of her crew and military ships are war graves under international law and are protected sites. Force Z (HMS Repulse and HMS Prince of Wales) have been almost completely destroyed due to the shallow water they sank in.
I do love me some Helen Mirren. She still a fox too.
Also don't tell me that I wouldn't click on a video titled "Why steel-making is sometimes done with pure oxygen in a clean room environment". You don't know me.
Damn. I have like 6000lbs of train track from the late-1800s laying around and I got really excited that I had a payday stacked behind my shed. Then you had to go a kill my brand new dream.
Ah yes, the Bessemer process, what makes boxes of knives...
Beams that can be melted by jet fuel😳
i had no idea there was actually like a seperate market for pre-1945 steel and even other metals
this is some timeline-shift level weirdness shit rn
for one of the first times ever I actually know where this one is going (spoilers)
Its for geiger counters and other things that need steel that isn't radioactively contaminated
That WWI joke at 3:01 is the funniest thing I've seen all week
Without watching the video, I'd guess it's because it's missing the trace levels of radioactive content in the modern era when trace levels of radiation make a difference to sensitive equipment. Am I right? Or should I watch the video?
makes you wonder what else we've done before realizing we've fucked a lot of shit up on accident
2:30 That hits too close to home, lol. I was trying to date a girl and it came up that she thought 9/11 was an inside job and the steel beams wouldn't melt and stuff. So that clip brought back a now funny memory (not at the time, though)
She's a keeper
@@hmmm3210 Yeah no, she's crazy
Marry her, she's a keeper.
well she's right, jet fuel doesn't even get close to the temperatures needed to soften steel, the twin towers were actually build with plane attacks in mind and would be able to resist them, the most likely scenario is that thermite bombs were used for which there are indications on footage but we'll never know what really happened excapt for the fact that the planes alone weren't the ones who destroyed the towers and that something else helpt with that
Sooo... if you don't want her, can I have her number?
The part you might have mentioned is that the pre-boom steel is so valuable that breakers have been disassembling ships marked as war graves. Most of the ships from Scoppa Bouy had already been recycled.
this was, at the very least, 3/4 as interesting. it reminds me of an incident in Mexico involving radioactive equipment being dismantled at a junkyard by unqualified workers, the "Cobalt-60" incident - there's plenty of information if you're interested.

And this video from another channel.
Do one on why TH-cam videos change their titles. This video had the title “why steel made before 1945 sells for 143x more” before i clicked on it and now it says “why steel from before 1945 is weirdly expensive”
"I mixed lead into my paint because safety first..."😂

2:55 lol I love how this is now the DeArrow title
I knew what this awesome video was about as soon as I saw the title cause I used this as my history essay in high school and I still find this stuff so fascinating.
I don’t think I would have understood the concept of WWII without the Shrek comparison.
It's called Scapa Flow, not Scarpa Bay
This video felt like going down a 50 ft tall steel zigzag slide, slamming between informative content and oversimplified absurdity. Honestly, I enjoyed it
i mean, germany wasnt really solely responsible for WW1, also, it was called the great war. how bad could it possibly have been?
Millions died

Not sure how accurate this is. The steel making process shown, blowing air through molten pig iron, is the Bessemer process, which has been displaced by the basic oxygen process. There was also an error claiming that the pig iron had to be melted, when in fact, pig iron was almost always taken directly from the blast furnace in molten form and then blown with air to burn out the carbon. The problem with the Bessemer process is that the nitrogen in the air made the steel brittle. I do not know what process is typically used to obtain the oxygen (cryogenic, pressure swing absorption, etc.) and what the residual carbon dioxide content is.
Adam Chase! Thank you, the writing is hilarious.
The amount of sarcasm in this video is on par with the levels of cesium-137 and cobalt-60 in the atmosphere before 1963. Understandable
This is one I learned from Citation Needed. Thanks Tom!
"Jeremiah World War I" is such a dumb joke that still makes me laugh
Ah yes when you know basically the entire story but still watch the video for the witty jokes.
I was wondering why companies were mercilessly scavenging WW2 shipwrecks (gravesites) in the Pacific. This is why. Astounding that I am mid-40s and never knew this.
4:05 computer ships
Also frustrating for archaeologists, nuclear bombs raised the level of carbon-14 in living beings, which is used to carbon date organic samples
Worked in a steel mill for 35 years. It had a state of the art Basic Oxygen Furnace way back in beginning of the 70's. The scrap steel used in the mix was sorted and graded. The company made excellent steel. Problem was the flooding of the markets with offshore Chinese steel, that had all kinds of crap in it but the bottom line always wins and manufacturers bought the foreign steel for cheap and the government only action was to spend years in delayed trade dispute talks that would result in a small fine, but even that windfall did not go to the injured steel industry but into the governments general funds.
This is off the ops topic but it is relevant.
Yep.
Imagine how much old steel were ruin to make scrap in China during the great leap forward
Congrats, you successfully talked about steel for a total of 2:28 before the inevitable everyone knew it was coming “Jet Fuel Can’t melt steel beams” joke.
1) It amazes me how useful your Shrek analogies are, especially since I never saw either of those movies and couldn't even make a decent guess about whether or not there was a third. 2) In your defense, the world has never been quite the same since Dame Helen appeared. If you'd told me cesium-whatever sprang into the world the moment the doctor slapped her on the ass to get her lungs going, I'd have believed you, probably.
You could say steel today is a steal. 😜
Without that Shrek comparison, I would have been completely lost on the second half of this video.
Plutonium 139 would be incredibly interesting, in that something that proton-heavy would have a half life somewhere around a picosecond. Your team needs to fact check a bit more, as the same typo got past the writer, editor, animator, and presenter.
1:48 excellent deadpan delivery
