Best simple explanation I've ever seen. Thank you. Ive made knives since i was a kid and im 40 now. Now i can show people in the auto shop i work in and maybe theyll understand why my chisels stay sharper than theirs. Lol
Really great tutorial. I never understood why heat it red hot, quench and then do same for desired hardness. Why not just quench when heating up to right color first time?
Does the metal become brittle after this process? I have a spring that works essentially like a clothespin does, but the steel rod will break if you bend it back and forth a few times. There are different treatments, but I have no idea which is the right one. This process in the video might be it. Thanks!
The metal becomes hard but brittle after the first dip, and then the second dip takes away the brittleness. I'm just trying to work out how to do this so I can DIY a metal stamp.
To really make the steel strong as well as hard, you would use white carbon powder, when the steel is red hot just B4 melting you dip it in the carbon powder and the steel will absorb the carbon creating a high carbon strong steel, such as what is used for driving wedges under extreme compression. High carbon tempered steel.
@@johnkomosa9508 Could you mix your (peanut)oil with for example charcoal powder for extra carbon? If there is more to spare it should take in more? Complete metal-noob here by the way....
Yes they won't harden it very much. Depending on the current hardness of your metal, it might actually get softer. Heating and letting it naturally cool normalizes the steel.
I have been thinking about making some log tongs and Log grabs for some tractor logging on the farm. Will use some mild steel. What would you recommend on how to harden them? Will be hitting the grabs with a skip hammer.
Gold. Steel and and bronze have the lowest heat conductivity while gold is near the top in metals. Also golds melting point is around 600F lower than steel.
@@KC.45 He's wrong you know, the answer you seek is silver, silver the most conductive metal for both heat and electricity, and also the most reflective of the metals.
Spanners are heat treated during manufacture, using tightly controlled furnaces and time tested methods. This process is best for making custom tools or maintaining cutting/punching tools. Heating manufactured tools up could cause them to become unsafe or weak. I guess you could try it if you don't mind losing one spanner, but there are a lot of nuances even in quenching a piece of metal correctly. Good luck
Leave a thicker edge, as in, don't sharpen to your finished edge dim. This could encourage cracking. Oversize the edge thickness to 1/16 inch at minimum. Get it red hot, test with magnet, and quench it tip down in oil, peanut or avocado oil so there is less smoke. Don't wave the flat end of the cleaver into the oil or you will potentially warp or distort the cleaver shape, because of the pressure differential. Remove scale from the hardened piece with a wire wheel, then temper the edge as shown in the video, seeking the straw color. Finish grind cold and never let the material get hot enough to discolor or you will need to repeat the entire process to achieve hardness.
Generally a bad practice... But everything changes steel to steel.... With some you are right it doesn't truly hurt except it may add some additional stresses to the work piece although it would increase chance of crack or warp which can happen when your correct quenching medium is properly treated.... Others however the second quench would only reharden the piece.... It's always best to know your steel. Whether by reading about it, or testing it yourself.
Excellent question. Who knows, lol. The core is very hot but also experiences such huge pressure. It may be solid or in a superionic state which is like a state in between solid and liquid. This state also has high electroconductivity. Perhaps that's another factor in a dynamo effect, where the different layers of the core could produce and build upon the total magnetic field. We don't know what the core is like exactly and are just starting to explore it better.

Simple, quick, and no BS explanation. Great video!

Just used this to make a custom carriage bolt, came out black after using engine oil. I love the finish so much.
Very informative. I have never heard it expressed so well.
Thanks Mr. Hock for taking time to explain in such a understandable manner.
Lmao probably not good for my marriage got you a new sub. Great video and informative.

I plan on heat treating tire chain links that I've welded, thanks for the info!
Two questions;
1.) how wide and thick is that piece of steel?
2.) how long does it take to get to temperature before the quench?
Can you also show us how to heat treat steel or stainless steel wire or springs?
Best quick straight to the point
So steel is not supposed to be red hot when you put it in water or oil?

This was so helpful thanks Mr white man but I have one problem how does the oshit colors burn so hot with the rainbow
good video , I never quench when I draw back ,or temper. I either turn off the oven and let it cool slowly cover it in hot sand and let it cool
Awesome thanks. Very informative demonstration and explanation.
"I'm doing this indoors, which is probably not good for my marriage"
How's that marriage doing haha
The fact he wasnt worried about the dangers lol and more worried for his wife 😂
The fact he looked like he wasn't worried about the actual danger and he was more worries about his wife is funny 😂
Nice demonstration Ron. Thanks for the explanation.
Did the quenching have a different effect than if you just let it cool naturally
Yes they won't harden it very much. Depending on the current hardness of your metal, it might actually get softer. Heating and letting it naturally cool normalizes the steel.
Can I do it with rather big padlock upper part or it is rather too big detail for that method?
Great Video! But why not use water instead of oil?
Depends on the type of steel, i believe the O in O1 means oil hardening
Love it… great video.
🇦🇺🤜🏼🤛🏼😎🍀
I’d like to see a Rockwell gauge comparison one day. 😊
So make it red hot, quench it in the oil and then make it hot again and cool it down slowly?
No quench again after the second time
Ron - why OIL vs water (or even dirt/clay)? --Loved the scientific 'Oh SHIT!' colors.... I've seen them too often.
The 0 in o1 stands for oil at oil hardened.
I have been thinking about making some log tongs and Log grabs for some tractor logging on the farm. Will use some mild steel. What would you recommend on how to harden them? Will be hitting the grabs with a skip hammer.
You can't harden mild steel. You can case harden it by soaking at red heat in a carbon rich atmosphere, like graphite etc.
I have a question.
Which metal heats faster, Gold or Steel?
Gold. Steel and and bronze have the lowest heat conductivity while gold is near the top in metals. Also golds melting point is around 600F lower than steel.

@@leinad.s I wouldn't say he's wrong. He never stated anything about silver
“I’m doing this indoors which is probably not at all good for my marriage .“ 😂😂😂
That's good woodworking.
ty for this video , now im gonna make bullet
I have a question! Would this be dangerous (er, more potentially dangerous) if one has a peanut allergy? Does the peanut oil become a vapor?
Linseed oil is what I use and it works well
you are an expert as you know heat is more at the tip
Great video with well presented information thank you kindly!
Can it be Anieled again to say work it then rehardened?
So could i do this on spanners to strengthen them even more ? Or does it get a whole shit load more technical than that

Why other people uses micro wave open after the heating process?
To leviate the internal stress of heating, and make it balanced
WHERE is it hard!? Doesn't look like like on the end, so how would that be useful behind the end?
I'm making a meat cleaver from AR450. Can someone give me tips on hardening this steel?
Thank you

You should try coconut oil and cannabinoid oils you'll reach a much higher flashpoint
Can a hardened steel be rehardened ?
Yes u can do it 3 times after that u can’t
Thanks
Avocado oil has a higher smoke and flash point.
I'm here because of I wanted to know how ro increase strength of iron nails, can anyone tell me how to do it
Good to know, thanks.
Thanks for this video.
RED THEN WHITE 😮
why are people talking & typing about temperature without putting the unit after? degree what? degree celsius or fareinthigh?
Just an fyi do not quench after your temper... It nullifies it
Would it be better to let it cool on its own? I'm curious

@@aaronstephens4212where can I learn about doing this to 4140
If steel/iron becomes no -magnetic when glowing red to white hot explain the earths magnetic core??
Everything has some amount of magnetism,
At incredibly large amounts, that small amount amounts up, but that’s only one reason.
Excellent question. Who knows, lol.
The core is very hot but also experiences such huge pressure. It may be solid or in a superionic state which is like a state in between solid and liquid. This state also has high electroconductivity.
