Hello All, does anyone have any ideas on japanese heat treating methods? As in what to use for the coating? Scott Slobodian says satanite or AP36. However no one in my area seems to know what this is. Is it a fireclay or a heat resist as used in welding? Any ideas would be greatly appreciated.

Look for an A.P. Green refractories distributer should be one in okc. I have a formulae using clay and wood ash, another method is to use furnace cement, fropm the hardware store. I'll try to look up the formulae and post it.

they still make satanite. I like it better than the #36 by far.

potters clay mixed with AlO and alittle crushed charcoal will also work.

The Japanese use clay, chame (remains of the polishing stones as they wear away in use, or AlO) and charcoal powder. I use graphite powder in place of the charcoal (planter plate lubricant from the farm store).

Don't over heat the steel, warm the water a bit, and you don't need much clay. You are only delaying cooling a few seconds. Good luck !

Good luck

The satanite is simpler, and works fine.
 
Again I need to say thanks for all the helpful advice.I can't say enough about the forum and especially the great people in it. I will let you know how the knife turns out and try to get a picture up. Thanks again guys

There's an interesting article in the march '96 issue of Blade Magazine called "How to heat treat and get an attractive temper line." The technique uses furnace repair cement. Food for thought.
