- THIS IS PART ONE OF A TWO PART VIDEO ON THE HEAT TREATMENT OF STEELS THAT EXPLORES THE THEORY BEHIND DIFFERENT TYPES OF HEAT TREATMENTS. HARDENING (QUENCHING), TEMPERING, ANNEALING AND NORMALIZING OF STEELS ARE PRESENTED AS SIMPLY AS POSSIBLE. MARC LECUYER
I have been a Mould Maker for most of my 62 years of life and you have put together by far the best presentation on the hardening of tool steel yet. I have been shown since my early apprenticeship years, by experienced Journeyman Mould Makers, an unclear method of oil hardening our tools. You have explained it way better than it has ever been explained to me before! Thanks! i can't wait to get back in the shop and practice on some tool steel.
Thanks James, I do this for fun and for the pleasure of helping others. Ciommenst like yours make the whole endevor worthwhile. I am touched. Thanks for watching and for taking the time to write, Marc L'Ecuyer
Your students were lucky to have a teacher like you, good teachers don't get enough respect IMHO.
if i only found this video sooner, instead of 100 other, informationless vids... tnx for the knowledge sir , great video
I am a retired Fire Chief, I wished I had your vedio when I was a new firefighter. You provide a perspicacious presentation that is concise a understandable. Superb.
Thanks abby! Flattery will get you on my good side! Marc
Thanks for your insights.
My maternal grandfather was a black smith. He told me he was apprenticed to three different men. In each case, when it came to performing a critical operation they would turn their back on him so he could not observe. Being a good student of the College of Hard Knocks, he went around them by reading books at the library. His understanding became greater than theirs. An unconfirmed family story is that he was the preferred sharpener of bits for the Mount Rushmore project because his bits stayed sharp longest of anyone's.
+Dennis Goodrich Sounds like a classic case in job insecurity, if you ask me. Your grandfather was wise to glean as much from them as he could, which sounded like the very basics...and then educate himself with more pure knowledge unspoiled by opinions. They actually created a better blacksmith by trying to limit his development...nice.
That is the best explanation of the basics that I've seen.
Thanks, Marc!!
answered all my questions I ever had about hardening thank you so much.
Great video! You've taken all the mystery and magic out of basic heat treatment - applicable to the vast majority of shop projects. Thank you!
very good basic information video thank you for sharing your knowledge and experience very welcomed amongst all the rubbish on youtube
This is my favorite part of UA-cam.
Them you for making this video because it's exactly what i was trying to learn
Awesome videos, Marc! Very thorough and well presented. I feel like I'm armed with plenty of knowledge now on steels and hardening for my home shop use. Thanks!
Best video on heat treating I've ever seen. Very easy to understand. Outstanding!
Thanks for breaking it down to an definable and understandable level.
I’m just so mind blown by this channel. I’m going to try to watch everything from the beginning to present.
Great job, Marc! Best explanation that I've ever seen of this rather complex process.
This is the knowledge I was specifically looking for. I look forward to your other videos.
Absolutely FANTASTIC video!
Stellar explanation of these concepts. I have read it a dozen times, but never has it been so obvious as your explanation.
I appreciate you taking the time to educate us on the properties of steel.
This is the best technical explanation of these processes I have ever seen. Well done.
Just found you and looking forward to watching all of your vids. This is invaluable information delivered in a "classroom" type technical way without having to study over pages of material. Your delivery makes it feel almost intuitive despite quite the opposite being the case. Thanks you.
Absolutely fantastic lesson. Have been in engineering over 50 years, still enjoy it. Thank you.
Best exposition of heat treatment I've seen.
Excellent video......No blabbering and right to the point with facts in your face. I learned a lot from this.
the most informative video in a long time
This is BY FAR the most informative video I have come across. And I have have watched days worth of video. The way you explained it made it extremely simple to understand and learned some new terms at the same time. GREAT VIDEO!!!!!!!!!! Thanks!
Absolutely brilliant movie, thanks so much Marc. Excellent detail and so well explained, by far the best movie on heat treatment of steel, and of any material, not only on steel but of any material!
I work in the demolition industry and have cut ALOT of steel over the years (oxy/LPG, thermal lance, hydraulic shears) and love every minute of it. We are taught about heat affecting steel lifting equipment(chain, hooks, FSWR) in Rigging, so I have always been aware of the topics covered above in a broad sense, obviously for the safety factor. This video has just added another dimension to my way of thinking about the whole experience. Literally another dimension. Thank you so much for sharing your immense knowledge mate. Appreciate it.
Comprehensive!
Beautiful!
Excellent video. You haven't said too much nor too little, and it was easy to understand. One of the best instructive videos I've seen on UA-cam so far. I wish there were many more teachers like you. Keep up the great work!!
Very well instructed! Thank you for taking the time to do this.
Thank you VERY MUCH. This is invaluable information on a complex subject, so expertly presented to make it comprehensible by us non professionals!
Over and above, I can only imagine the amount of preparatory work that goes into each one of your videos so they are as precise, flowing and smooth as they are.
My sincere congratulations, please keep up you excellent work.

Marc: Thank you for this excellent presentation on heat treatment. You have explained to me in a half an hour, what 2 years studying books could not. Thank you very much. I'm looking forward to learning from your other vids. Thanks again for sharing your knowledge....
Best tutorial on YT for heat treatment
Solid gold lesson, thanks Marc!
This is a great video! I learned a lot from this. Thank you for making this, Marc, it revealed a lot of the mystery of heat treating.
excellent Marc, as always!!
...I'm investigating how to fabricate some spring clips to stabilise a baffle assembly in a telescope - and here I discover yet another youtube gem video. Thorough and clear, many thanks for an excellent video, a classic. I've watched many videos before this but none embed the presented phenomena and techniques in a rigorous empirical & scientific demonstration as your video does. A classic. Thanks kindly for your effort.
thank you for your response Marc. I will try this later in my class.
Thank you for the video it is by far the best and easiest explanation I've ever seen on you tube.
This is an excellent video. Very easy to understand and tremendously informative. I wish I had been able to watch this 20 years ago.
I had some fundamental question concerning heating my 4130 alloy. You provided very good instructions on heat treating, tempering, annealing and quenching. Straight and understandable explanations to the process. Thanks!
Señor Marc , muchas muchas gracias de verdad por compartir todo su conocimiento. He aprendido mucho de usted y soy su fan y lo admiro, espero conocerlo algún día en persona. Greetings from México 🇲🇽. Viva Canada 🇨🇦!
Awesome video! Ive been trying to find a detailed video explaining these processes for a couple of weeks now. Well done and thank you very much!
Excellent video. Everything you need to know about steel heat treating in one place. Thank you very much for taking your time to record this.
I need to heat-treat some steel for carving tools i'm making, and this video was just what i needed.
Best regards
This is really great stuff. Thanks for sharing.
Thank you for this video this is some of the best info I have seen here on you tube.
I have just gotten into your videos and already I want to thank you for giving clear and simple explanations of fundamental matters in working with metal. Many of the UA-cam videos give very poor explanations of the things in their titles and I'm not sure why people bother to produce them. Not all of us have fathers who worked forty years as machinists and not all of us have access to a fully equipped professional machine shop. Thanks again.
Don't know 'bout that music, though.
Thanks a lot for covering this process so methodically and presenting it so absolutely clear. Its easy now for me to chose the best way of hardening and tempering the little anvil I am making with a bar of st 37k steel. I was under the impression that tempering after hardening was not needed. Now I know better. Thanks for sharing your knowledge with us.

I saw some comments / critics to your video.
I give al lot of musical and technical workshops. All I can say you have given me, and others, an example on the best way to make things understandable.
What a brilliant lecture from the professor of metallurgy. THANK YOU
Marc, Great explanation. Thank you for taking the time and sharing... Chuck.
I've read about austenite, martensite etc. decades ago but now I really understand what it means. The 1-2-3-4 rod was really descriptive what happens inside steel when heating and quenching. This was by far the best educational video I've seen for years in UA-cam. I have to check the other videos in your channel too!
+Roos Teri Thanks Roos, you can link to all my video on my free website THATLAZYMACHINIST.COM Thanks for watching and for commenting, Marc
Just what I needed to know. Thank you so much for doing this video.
Thanks a lot for sharing info. This is my favorite video clip.
Thank you for the best presentation on hardening steel. Now it is making sense to me, great job.
This is FANTASTIC. Finally, I’m understanding this topic due to this excellent explanation and demonstration. THANK YOU SO MUCH!!! Even with an engineering background, I’ve never experienced such clear as this instruction.
I feel lucky because you are still teaching in this way. GREAT VIDEO AND EXPLANATION.
Incredibly succinct and informative. Thank you
Finally, I understand this topic. Thanks! great tut :)
Outstanding vid sir! Your graphs and explanations made more sense than any I've encountered to this point.
Wow, good information! He sure knows his subject!
Thank you very much for this tutorial, it nicely and concisely tells me what I was looking for. It's much appreciated.
Best video about hardening and tempering
Clearest and best paced explanation I've found...thanks for posting
That’s a lot to take in, thanks for the teaching, your a modern day Tubelcain. Thank ayou.
Great video. Great info. Thank you for sharing.
thank you from Iran for your valuable presentation
Lazy - You make good informative videos - I love them...your presence is weird enough, and your speech clear and succinct enough, as to add an X factor to your videos that is pretty cool and above the normal BS on YT..thanks..I love em
What an amazing and instructive video! Thank you very much!
That entire presentation is just brilliant, didn't need complex tools or measuring equipment and the visual differences are clearly identifiable, it's like advanced metallurgy for beginners, provided in a way that we can understand.
You are an excellent teacher!
Just found this video. Great info and thanks for examples to help show how things work!
Great video. I was amazed at the differences in the crystalline structures..
this vid is by far the most detailed and correct vid i have found so far on this subject, and for that i thank you. you have made my day!!
well done sir.
+stu smith Thanks Stu! It's all for fun but it is nice to know that the videos are appreciated! Marc
Wax on, wax off. Paint the fence. The way it should be taught. Thank you for not skipping over the in depth details with proper terminology.
Thanks! It's all for fun and it is nice to know that the videos are helping, Marc.
great school video, as not native english, I appreciated a lot your efforts to speak slowly.
I may say it's the best video on youtube about this steel heat treatment
I'm a machinist send most of my hardening out but have strongly considered getting into it myself. Been thinking about marketing some knives. Your video is immensely informative 👌 thank you Sir!
Some great knowledge,documented!
Wow that helped me tie years of info together! This video will really help the intermediate black Smith engineering student as much as beginners
thank you again!
I'd pay good money to attend one of Marc's lectures. Very informative, very well done.
Outstanding teaching video, the best I've ever seen.
Sir, Thank you. Wonderful lecture. Never felt tired during the entire lecture.
May god bless you.
Vrh vrhova !!! Svaka cast !!!
It took me a few minutes, but I found the translation. thank you for watching my videos, I am glad that you enjoyed them. Marc L'Ecuyer
Thank you. We watched your video today in welding class. The information is great!
Hi Patrick! I am happy that the video helped and even happier that you took the time to write. I produce the videos for fun but it is nice to feel appreciated. Good luck with your studies, work hard and be safe!!! It is worth the effort, being knowledgeable and good at something makes a real difference in life. There are a lot of mediocre lawyers (some good ones to) out there but very few top notch welders.
I would recommend this video to be shown at material basics classes in mechanical universities! It really explains well the principles of heat treatment, which are usually too boring, without practical experience. :) good job!
Excellent video. Clear and concise explanations, nice examples, and not too much information at once. Excellent. Thank you so much, I learned a lot watching it. ...continuing to part two :)
Wow, I agree with the previous post. This is the most informative, professional and concise video I have seen, as opposed to a sea of rubbish.
This is high quality teaching! Great video, very insightful and brilliantly explained topics. Well done, sir!
Very clean and understandable tutorial! Thank you very much!
Thanks for this, I have watched it a couple of times.
Best explanation I've ever had about heat treatment
Thank you very much
Amazing video. I really enjoy them.
Thank you for the VERY informative video. Long back, I took a few material science classes in engineering school ( my major was electronics engineering) - and your video really clarified so much of what I did not quite understand back then.
Thanks for the link to your video, Very well done. I taught metalwork for years so I have some knowledge. wish I had your video years ago, that was before internet.
This is an amazing video!!! Thank you!
Un video muy instructivo. Muchas gracias por mostrar el efecto del calor sobre los aceros, para la formación de microestructuras.
Wow.. I actually understand!!! know you're gifted
I'm not really a metal worker but in general working with steel and hardening has always been something I have been curious about. I looked through a few UA-cam videos tonight and did not come away feeling like I have learned much, and in general felt somewhat disappointed in most of what I was finding. But then I suddenly found your video. After having watched all of your video, I now feel like I have actually learned something. I feel like I at least understand the basics now. Thank you sir for making this video. You are an excellent teacher and I feel happy to of (finally) learned something new today. I have saved your channel and I will return to watch some more of your videos later when I have more time.
Thanks Blueberry! It's all for fun, Marc
Holy cow this is informative! Thank you!!!
Thank you for the comprehensive video. Very easy to follow.
Excellent instructional videos for sure. I can’t the believe the youtube algorithm didn’t introduce us years ago.
