Steel Heat Treatment Explained

- Heat treatment can dramatically affect the strength of steel. This video demonstrates and explains the effects common heat treatments have upon a medium carbon steel. In particular, it explains what heat treatments do to the steel to provide such different properties such as strength and ductility.

Why this channel is not getting an insane amount of views is beyond me. This information is gold. Especially for people that have basic understanding of the matter, but do not want to dig waist deep into the literature.
Your words reinforce why I'm doing this - to help add on to people's practical/useful knowledge, not bury them in theory. I hope time will draw out that 'insane amount of views'. Please tell google to share this with everyone.
A big problem might be that notifications for new videos (bell) disable themselves whenever I try to turn them on...
@@steini19o4 I think I may have found the problem. Does it work now?
@@Shane_at_SteelImageEdit: It works now after unsubscribing and then re-subscribing. Thank you
@@Shane_at_SteelImagebeat me to it. "give it time" was my first thought before seeing your response. Last year was when I first stumbled upon Hardening, Tempering, Annealing, and Forging of Steel by Joseph Woodworth and was captivated by the subject immediately. Seeing the birth of this channel got me excited for future uploads. It's only upwards from here on!
Super clear explanation, one of the best I’ve seen!
Wow, thank you!
Brings me back to my days in the QA lab at a heat treatment facility. I always remember martensite as it has that thatchy/woven look to it under a scope. Great video!
QA lab - I'm sure you saw this daily! Hopefully fond memories not bad ones.
@@Shane_at_SteelImage great memories!
THAT! Was an excellent explanation! Thank you. Please keep going. Maybe compare 1045 to other steels and their heat treated properties. Like 1095, 4140, and throw in some tool steels too. Thanks again!
I'm actually doing that now for my next book (1015, 1045, 4140, 4340). Might be possible to sneak in a video at some point.
Great video as always! Heat treatment has always been a bit puzzling to me as a lowly mechanichal engineer, so the explenations presented here are really helpful! Here's an idea for a future video: how do the different alloying compounds such as chrome, sulfur, phosphorus, etc. affect the steel's properties? Never had em all explained in detail before, so a video on that would be great!
Really glad this helped things come together. I would be interested in explaining that... but it might be a while.
In the interm - chromium has the benefit of both (a) increasing steel strength and (b) increasing its hardenability - the size/thickness we can quench into martensite.
I realize you're asking for a lot more than that. Yet I've already started to put together the materials to begin tacking 'toughness' next.
If you didn't get the notification when this video was posted, try unsubscribing and re-subscribing. I can't take credit for coming up with the idea, so don't ask me why it works.
Thank you!
Excellent, concise video.
Thank you.
Amazing video Shane
Thanks Dave!
Awesome video. Please do a follow up show examples and applications of each type in the real world.
Glad you liked it.
Hot Rolled Condition:
Shafts, machinery housings.
Normalized Condition:
Crankshafts for engines.
Hydraulic cylinders.
Many machinery components.
Annealed:
Not used in this condition. Purchased in this condition, machined and then heat treated to a stronger condition.
Quenched and tempered:
Sprockets for conveyor systems.
Axles for trucks and trailers.
Small shafts.
Armor and defense applications.
Chat GPT helped with this answer.
i have bought both books and it gave me a nee dimension for maintenance repairs
I am very very pleased to hear your say that!!
Very interesting and we'll explained thank you!
Really glad it was helpful. I think most people explain heat treatments using relatively academic terms (FCC/BCC, phase diagrams, etc). Yet they seem to omit the most important part - what it does to the carbon/carbides and its role in strengthening. Anyway, I guess I'm glad this slightly different approach resonated with you.
It's funny, but as a former machinist, I could hold two piece of steel, one hardened and one soft, and could tell you which piece had been heat treated. This topic always fascinates me. Thank you.
@nobuckle40 - do you recall how you would be able to tell the difference?
@@Shane_at_SteelImage I can't really explain it. There is something about the way hardened material feels. Perhaps it has something to do with the way each material absorbs heat. All I know is that other machinist that I worked with said the same thing.
@@nobuckle40 I believe you. I'm curious about this. I'm going to ask around a bit, see if others feel the same way. Appreciate you bringing this up.
Great presentation! Thank you! :)
I find it interesting (and a bit amazing) that much of this is what a blacksmith might do by a combination of intuition/experience/feel.... working with a crude piece of metal of unknown alloy, needing it soft to work with, but needing some strength/hardness in the end product.
Chris, I fully agree it is amazing! Not only that, blacksmith of old figured out much of this long before science ever tried to explain it. Some people think our metallurgy practices were developed by engineers and metallurgists. But its the opposite, engineers/metallurgists have tried to understand and optimize what tradespeople had been doing for centuries.
Detailed explanation!
Glad you think so!
Awesome. Great content with clear concise explanations. Thank you.
@terry9397 glad you found value in it! Thank you for taking the time so say so.
Great work!
Thank you Jean-Christophe! Really appreciate you saying so.
this is very good work. would you consider doing a similar video on stainless?
Very much so. There is so much I want to cover (next is toughness). If there remains interest, I'll keep going and include some about stainless.
Oh man, i can´t wait for it. This video is really amazing for the great information and the clarity in the explanation. I subscribed because you have real knownledge on this matter. Thanks for your effort and dedication to promote this piece of science. Greetings from Spain.

I think I may have found the problem. Is it working now?
