Here is the link for Part 2 of this video -- • CASE HARDENING Carburi...
This is part 2 of a 2 part video class on CASE HARDENING steel. Also known as SURFACE HARDENING or CARBURIZING. This process allows you to surface harden low carbon/mild steel such as 1018.
I will use KASINIT (no longer available) powder in this demonstration.
SUBSCRIBE if you enjoy the content! I have over 1200 other shop videos.
I have tubalcain tee shirts available. Visit STOREFRONTIER and search tubalcain!

I was in the last class(in my high school) that even had "shop" classes I learned more in my metals, woodworking, and electronics classes that I still use today than many people will ever know about these "basics" So sad. Thanks for being here to help educate our youth.

Excellent video,Mr. Pete.I´ll like to mention two things.First thing is about quenching deformation because of the heat shock.Second thing is that as compared to other case hardening methodes that I´ve seen ,the piece plus the hardening mixture,both go into the oven in one take and after heated they go to quenching .There is a video in Antiquitera(not sure the spelling ) that tells you how they did it several thousands of years ago.Thank you.

A somewhat similar method of hardening the outer surface cast iron has been used by the Corliss Safe Co. Since cast naturally has a very high level of carbon in the mix, none has to be added. It had to do with how the iron was cooled. Instead of pouring the cast into a sand mold, steel molds were used. Well I think they were steel, but for sure they were metal, which caused the metal to cool very quickly. This caused the outer surface to be quite hard to prevent drilling, with the drills available at the time in the 1870's. The resulting metal was called white cast iron.

Great video on heat treating, Just like the shopkids, people love fire and explosions.! The process can be used to make cutting tools. But you have to harden multiple times to get the case deep and of course, pregrind the tool so that only light hoaning is required to touch up the edge. Of course, when you regrind the tool is toast.

MrPete, Lyle, your videos are the only one on the internet that describes the processes so well that I can actually replicate them in my home shop: A shop I do not believe would have grown or evolved into such a useful space, or with the Journeyman skilled carbon based life form in it, without you! Please keep making long videos with actual usefulness. I am sorry if they do not make you rich, but Lord as my witness you enrich the world. Have you considered an Anthology? A USB drive with all your videos on it is something I would pay for! My alternative is to pay a software company to buy their product and use it to download all your content. Paying you is a much more attractive idea. a PS to a long post - I love my T shirts from you!!!

About a thousand years ago while attending a technical collage I took 2 semesters of metallurgy. We had an "always hot" caldron of cyanide salts at our disposal. when our mild steel high school projects reached cheery red and quenched in a salt brine a very pleasing color case hardened finish was achieved. Mauser military rifle actions were case hardened.

In shop class,, 1961, I made a scroll bender. We case hardened in a small gas fired "box". Cherry red and into the carbon stuff and back into the gas fired box. Then the water dip. The box was also used to heat a large copper soldering iron. Used that iron to solder parts we made out of tin cans. Parts were made using sheet metal layouts techniques. I made a water sprinkling can. "In the old days" we were taught how to use our hands and minds more. We had auto shop, wood shop, electrical shop and metal shop. I even spent a week in Home Ec. made a great cinnamon roll cake.

I learned how to heat treat on another video on KZbin. I use a small charcoal grill mounted on a V-shaped stack of bricks and use a fan to force air up through the bottom vent in the grill. I heat the metal parts in the charcoal to red hot, then quench them in used motor oil that turns them black and rust proofs them. Then put them in the oven at 250 degrees for 1/2 hour. and let them cool off.

This has been one of your best series ever! It's a topic near and dear to my heart, and the more you want to do on it, the more I'll watch. So, the reason that I'm really interested in this entire process is that it provides a functional finish on a part, using not-too-horribly dangerous reagents and you can get beautiful parts this way. Actual black oxide finishes are way too dangerous to attempt in a home shop; even the medium temperature processes are still running very hot lye solutions. The cold blue finishes just don't seem to be very effective, and I'm a bit concerned about the selenium in them. The classic case hardened finishes using charcoal and heat seen like a total win for the home shop, with parkerizing perhaps a second. The thing I really want to try is color case hardening with charcoal, which I believe you do pretty much the same way as this only seal it up in an stainless full envelope.

You can place the piece inside a larger box, filled with coal. The box must be closed to maintain the internal atmosphere with a good level of carbon. The ideal is to leave it in the oven for at least two hours, to form a layer about 0.3 mm thick. After half an hour, the layer is no more than 0.05 mm.

Thanks fort another great video tutorial. With regard to other methods of case hardening, The Machinist's Third Bedside Reader has a good story with information about color case hardening with Bone Black. essentially burned, ground bone meal, which can be made at home or purchased ready made. I believe it is used as a colorant for dyes. I'd sure like to see a project about making a steam (compressed air) whistle similar to the one at the end of your video.

I think it would be interesting to compare how the file cuts and sounds on the case hardened and non case hardened pieces.

That process would be great to use on garden tiller tines or hoe blades. Keep up with the great videos. Always sharing and waiting for new ones.

I once read in a model engineering magazine that it was possible to do case hardening (at least to some extent) by using sugar. Sugar has a high carbon content that transfers into the first few microns of the hot steel. I've never tried it myself though.
