Basically the economy S/S , grade 430 , has NO nickel and it's magnetic . The higher grades , grade 304 and 316 are non magnetic . The 304 is used in better grades of commercial kitchen equipment . The 430 is in the economy equipment . Some equipment is mixed with a 304 top and 430 under shelf and legs . Or a sink with 304 bowls and the rest 430 . A 316 grade would have more nickel and be used in a commercial kettle lining to resist food acids . There are several other grades . Again , if magnetic , it's economy and you will only get a lower price as " steel " as scrap . The magnet doesn't lie . But people " think " it doesn't rust . But if abused , it definitely WILL . Salts , acids and chlorides will corrode it .
Good general basic but the magnetism part was not accurate. Magnetism has nothing to do with the quality and cost of stainless steel. There is another family of Stainless steel which has better performance against corrosion and strength. Its the duplex family. It's also magnetic. The popular grade will be the 2205. 22%Chromium 5%Nickel 3% Molybdenum. Same material used in building the Singapore Marina Sand's Helix bridge due to its superior corrosion resistance and strength (able to use smaller members to increase the aesthetic).
ty for the info, I though that steel and all the steel alloys are magentic, after all iron is the majority and the rest are just extras. Is there a way to determine whether or not a metal (or alloy) is steel?
@@sssteel99 The magnetic properties separates the economy from premium in the food service industry . I believe you have a special alloy for the application . With 5% nickel , I would guess it's non magnetic .
@billsmith2212 No, it's not. You need 8% Ni for the alloy to be in the austenitic phase. The crystal structure will then align in Face Centre Cubic formation and render the alloy non magnetic. At 5% Ni, the alloy will be in duplex phase. At this phase, the formation of austenic is incomplete. So you have a mixture of 50% Austenitic and 50% Ferritic. In Ferritic phase, the crystal structure would be aligned in Body Centre Cubic, BCC formation. Alloys are magnetic in this formation. Conclusion: With 5% Nickel, the alloy is magnetic.

"Stainless" is a misnomer as owners of DeLorean cars soon discovered. Stainless steel may be corrosion resistant but it is not "finger-print proof." The original "18Cr-8Ni" stainless steel composition was discovered accidently in Sheffield, UK, by a man named Brierly. He'd been doing some work with steel samples of different compositions that he'd left exposed to the UK's miserable climate. Some months later he found that all except one displayed surface corrosion. Quick analysis of the uncorroded sample and------- the first stainless steel.
I think Krupp in Germany may have had a big impact on stainless development, they were developing armor plate, and found nickel alloys had the toughness necessary for this service. This was around the turn of the last century.

After reading the comments I will say this - this is a good overview of the process. It will give anyone a good base to search out more in depth discussions on the process of creating SS and the different grades/types.
The chrome makes it hard to drill holes etc There’s magnetic and non magnetic .kitchen bench tops are non magnetic And fridges are magnetic , as scrap steel the the more chrome added the more it’s worth Also stainless has grain direction (like wood ) so it has to be be folded a certain way . It’s possible to weld stainless and mild steel together ,that is a little involved
@@stevenmonson5149yep not involved at all really. I'm a weekend warrior basement TIG guy and got mild to stainless easy. 309 is great stuff when you aren't exactly sure of the alloy you're working on.

What I kind of missed is any talk about the amount of carbon in the alloy, in so far as I know, carbon is an important element in this mixture with the alloy to become steel.
No actually steel does not have to contain carbon. In fact in many steel grades like stainless 304L, 316L and the interstitial steels carbon is kept down in the parts per million range.

We used to purchase Chinese stainless steel we had to do a Metalology test on every single batch to make sure it was up to a specification before it was shipped, once shipped it was too late they didn’t want to know, bye everywhere.
I was a metal fabricator in the pharmaceutical industry for 36 years working with stainless steel exclusively. It's not too much of a challenge after you come to understand it's properties.

It's not a challenge if you do it right, welding is awesome especially Tig, as for drilling make sure you have the right bits and slow it down and make sure you use cutting oil or coolant, and cutting it's not much different than other steel just go a bit slower and watch the cutting edge.
Thanks for the video. I use a Swiss electricians knife. It is stainless steel. But a magnet will stick to it. Know I have an understanding about the quality. Thanks.
Not to be nitpicky but your video made it sound like Pig Iron was pure Iron, but it's actually an alloy of iron and carbon. By definition steel can't be steel without carbon so I was a bit confused the first time I watched the video.
Great documentary. It is said that components are added to increase the steel's strength and hardness. Then how come that INOX screws are so much softer than normal screws? They are likely to snap when you don't drill a hole in advance. Just wondering.
It’s not just material components, it how the material is treated as well, such as heat treating and tempering or even chemical treatment , this is why in the US you can not use screws for timber framing construction, screws snap and shear, but nails bend without breaking, this I’d do to how nails are made by drawing metal wire through progressively smaller dies, there is no cost effective way to manufacture screws in this manner to impart the same properties that die screws does
So, comment at 3:48 the ingredients are “thoroughly mixed “ I’d really like to see how all these ingredients are evenly mixed. It sounds almost an impossible task to achieve a consistent product ??
How do they know when the correct amounts of added ingredients are achieved. That is, when adding nickel, even though they may drop in X pounds into a vat of liquid steel (Y pounds), how do they verify the exact correct ratio? Remember, the steel is 1900 degrees C. How is an analysis done at that hot temperature?
Same way as with any other steel: they take a sample (yes, this is possible. They use a small ladle with a very long handle.), poor it into a small mold, send it to the on-site lab, do a quick scan, and report back to the shop floor.
‘Stainless steel is not magnetic in most cases because the majority of commonly used stainless steels have an "austenitic" crystal structure, which due to its atomic arrangement, prevents the magnetic domains from aligning and therefore does not exhibit magnetic properties, even though it contains iron which is typically magnetic; this is often attributed to the addition of nickel in the alloy which disrupts the magnetic alignment.’
Martensitic and austenitic stainless steels are not magnetic due to the addition of nickel. Ferritic SS is magnetic and is the most durable, used always for knife blades.
If you mean the "cups" that the molten steel is transferred in to for transfer from the furnace, they are ladles (maybe also called pots). Refractory brick lined steel outer cases.
Stainless steel is a miricale steel, but used with a disimler metals acts of electrolisis take place.Such as stainless steel moldings on outside trim and fastened to steel? I t will rust right on through the steel. Even faster on a salt invirement?
When Boeing was building the Minuteman intercontinental ballistic missiles I’m pretty sure that’s the project. They were having problems with the storage tanks for the fuel having corrosion problems and there was this little steel male not so little but not as big as some in a little place called Butler Pennsylvania. It was arco steel they figured out the mix they needed to make tanks that wouldn’t corrode.
@@bobdevries4028 a scrap metal dealer told me that since there are so many grades, with different alloys, which lowers the value. What he wants are large quantities of the same grade, for example mill scrap.
Their is a grade of stainless commercially coded 600. It is fairly inexpensive and used in applications where it is painted, street furniture being a good example. Unlike normal steel. it still has a fairly high resistance to corrosion when the paint is chipped. It can also be used in street lighting applications. Not having the corrosion problems of normal steel, where rusting increases it's volume by 13, it can be used in reinforcement for concrete fence posts, window sills and prefabricated concrete garages. Normal steel in these application needs a minimum concrete cover of 2 inches. These 600 grades an be made from scrap. They were considered for car manufacture, but they were too brittle to pass the crash tests. When induction hobs were introduced, a normal steel plate had to be buried in the base of the pan. Unfortunately it's size and positioning can vary efficiently wildly. The early pans cost a fortune. During testing, Bosch tested a grade 600 enamelled Asda (Walmart in the US) pan that cost a fraction of the price. Having magnetic properties throughout it outperformed all the others and did not have the problem of hot spots. Unfortunately, the properties included the handles, which were reaching more than 300 degrees. So that was that. LOL

Joke's on you!!!😂🤣😂🤣
If we charged China (and their unscrupulus brokers) for all of the fraud & subpar production that they have flooded our market with, we could pay off the national debt...
We used to purchase Chinese stainless steel we had to do a Metalology test on every single batch to make sure it was up to a specification before it was shipped, once shipped it was too late they didn’t want to know, bye everywhere.
Don't forget Duplex

It is a challenge to weld, drill and cut.
I was a metal fabricator in the pharmaceutical industry for 36 years working with stainless steel exclusively. It's not too much of a challenge after you come to understand it's properties.
I endeavored to make small passive solar tanks - for hw, using two ss deep pans welded together. I was in Thailand at the time. A regular welder couldn't do it, so I found a specialist. He welded it, but it was costly. I had planned to make them to sell, but the welding cost compelled me to abandon the project. A search online reveals nothing as simple as a black ss tank for passive solar pre-heat of water. I'm 72, but if I was younger, I might re-devote my energies toward reviving that project.
It's not a challenge if you do it right, welding is awesome especially Tig, as for drilling make sure you have the right bits and slow it down and make sure you use cutting oil or coolant, and cutting it's not much different than other steel just go a bit slower and watch the cutting edge.
Those factories remind me of Freddie kruger or terminator 😅

9:15 I am Stainless Steel
I scrap metal. SS gets 30 cents a pound. Some " stainless Steel" sinks are magnetic with SS coating therefore low price in returning.
Thanks for the video. I use a Swiss electricians knife. It is stainless steel. But a magnet will stick to it. Know I have an understanding about the quality. Thanks.

It's the same recipe as regular steel, minus stains.
It ain't that it is actually stainless. It is just that it actually stains less.
Not to be nitpicky but your video made it sound like Pig Iron was pure Iron, but it's actually an alloy of iron and carbon. By definition steel can't be steel without carbon so I was a bit confused the first time I watched the video.
👍
Simple in our days😂👍
The more corrosion resistant SS is, the weaker it is. Stronger SS is less resistant to corrosion and is prone to rusting.
I think it’s 303 filler rods to weld SS to steel
Great documentary. It is said that components are added to increase the steel's strength and hardness. Then how come that INOX screws are so much softer than normal screws? They are likely to snap when you don't drill a hole in advance. Just wondering.
It’s not just material components, it how the material is treated as well, such as heat treating and tempering or even chemical treatment , this is why in the US you can not use screws for timber framing construction, screws snap and shear, but nails bend without breaking, this I’d do to how nails are made by drawing metal wire through progressively smaller dies, there is no cost effective way to manufacture screws in this manner to impart the same properties that die screws does
this is why hanging should come back
What you on about?
So, comment at 3:48 the ingredients are “thoroughly mixed “ I’d really like to see how all these ingredients are evenly mixed. It sounds almost an impossible task to achieve a consistent product ??
The AOD process stirs it all up in the furnace
@ AOD ?
Super interesting. So lots of tools say chrome vanadium or something like that. What is it and how's it made?
How do they know when the correct amounts of added ingredients are achieved. That is, when adding nickel, even though they may drop in X pounds into a vat of liquid steel (Y pounds), how do they verify the exact correct ratio? Remember, the steel is 1900 degrees C. How is an analysis done at that hot temperature?
Same way as with any other steel: they take a sample (yes, this is possible. They use a small ladle with a very long handle.), poor it into a small mold, send it to the on-site lab, do a quick scan, and report back to the shop floor.
@@wtflmaa7842 When you say "do a quick scan" what is the machine that does it?
@@terry_willis State of the art is mass spectrometry.
How is it non magnetic
‘Stainless steel is not magnetic in most cases because the majority of commonly used stainless steels have an "austenitic" crystal structure, which due to its atomic arrangement, prevents the magnetic domains from aligning and therefore does not exhibit magnetic properties, even though it contains iron which is typically magnetic; this is often attributed to the addition of nickel in the alloy which disrupts the magnetic alignment.’
Only the cheap sht is nonmagnetic
Martensitic and austenitic stainless steels are not magnetic due to the addition of nickel. Ferritic SS is magnetic and is the most durable, used always for knife blades.
How is SpaceX welding giant tubes without it warping????
No wonder why stainless steel is so expensive!
1:11 minutes to tell us that we are going to see how SS is made......Loves to hear his own voice, eh?
What kind of material are those cups that pour metal is?
If you mean the "cups" that the molten steel is transferred in to for transfer from the furnace, they are ladles (maybe also called pots). Refractory brick lined steel outer cases.
Why is it sometimes not magnetic?
austenite
General rule...stainless with Ni + Cr (300 series) = non magnetic...stainless with Cr but no Ni (400 series) = magnetic
The Cybertruck exterior was possible because of SS. Bring on the Cybertruck!
Stainless steel is a miricale steel, but used with a disimler metals acts of electrolisis take place.Such as stainless steel moldings on outside trim and fastened to steel? I t will rust right on through the steel. Even faster on a salt invirement?
How it is made? Exactly the same way as any other steel, just with different additives in different proportions.
I worked at a paint plant and I would take a piss in the finish product as often as possible
I do wish that you would have mentioned where stainless steel comes from my home city of Sheffield in England the steel City
Hilpert Extension
I have stainless steel glasses.
When Boeing was building the Minuteman intercontinental ballistic missiles I’m pretty sure that’s the project. They were having problems with the storage tanks for the fuel having corrosion problems and there was this little steel male not so little but not as big as some in a little place called Butler Pennsylvania. It was arco steel they figured out the mix they needed to make tanks that wouldn’t corrode.
There is a magnetic SS. I think a 309. 304 is the most common
Invented in England
It’s rustless steel ,not stainless steel . It will stain .
Just turn 180 and sum over there then.
I prefer rostfrei steel seeing my local climate
316 L flue liner you can easily check to make sure its not ss coated use a magnet true ss is none magnetic
Where is Carbon in this steel? I thought Carbon was a part of Steel- alloy.
One drawback to stainless steel is recycling; since the exact alloy composition varies, scrap stainless is not desireable...
I still get good money when I take it to the scrapyard.
@@bobdevries4028 a scrap metal dealer told me that since there are so many grades, with different alloys, which lowers the value. What he wants are large quantities of the same grade, for example mill scrap.
Their is a grade of stainless commercially coded 600. It is fairly inexpensive and used in applications where it is painted, street furniture being a good example. Unlike normal steel. it still has a fairly high resistance to corrosion when the paint is chipped. It can also be used in street lighting applications.
Not having the corrosion problems of normal steel, where rusting increases it's volume by 13, it can be used in reinforcement for concrete fence posts, window sills and prefabricated concrete garages. Normal steel in these application needs a minimum concrete cover of 2 inches.
These 600 grades an be made from scrap. They were considered for car manufacture, but they were too brittle to pass the crash tests.
When induction hobs were introduced, a normal steel plate had to be buried in the base of the pan. Unfortunately it's size and positioning can vary efficiently wildly. The early pans cost a fortune. During testing, Bosch tested a grade 600 enamelled Asda (Walmart in the US) pan that cost a fraction of the price. Having magnetic properties throughout it outperformed all the others and did not have the problem of hot spots. Unfortunately, the properties included the handles, which were reaching more than 300 degrees. So that was that. LOL
