Anyone have any experience with heat treating this steel? I sent a couple out to Peter's Heat treat last time I used it because the time before I failed miserably at the heat treat. My foil wasn't rated at the temp I was soaking at and it basically burnt up.

I think they make a higher temp foil, but not sure. I buy my foil from Knifekits. It's rated for 2000 degrees. I found out that's it! Don't go over. Period.

Looking for a source of higher temp foul and any advice. I'm sure this can be heat treated at home with the right foil.

I'm using a heat treat furnace btw. I plan on doing my own cold treatment with dry ice and acetone. I've done many steels this way with good results.

Any sources for the foil would be great

Hey, Chris, I've never used that steel, but I buy SS tool wrap from Enco. Their 309 wrap is rated for up to 2100 deg. I've only heat treated 2 SS, 14c28n and AEBL and both of those have an upper austenitize curve at 1975. The Enco 309 did just fine on those. Hope that helps.

Thanks Anthony. I'm afraid that won't get it the austenizing temp is 2150. I'm afraid at that temp for 30 minutes it won't hold up. Here's my source of the steel and heat treating info

Below is a copy from Carpenter's datasheet. I take it that the 2150 is for a furnace none of us have. Using our home shop methods, it looks to me like 2100 deg is what they are calling for. Atmosphere controlled furnaces would be about the same thing as tool wrap wouldn't it? Just a thought.

"Preheat to 1400/1450°F (760/788°C) and equalize. After preheating, rapidly heat to 1950/2100°F (1066/1149°C) when using salt or atmosphere controlled furnaces and 2050/2150°F (1121/1177°C) when using vacuum furnaces. "

It is Carpenter steel. 2150 is what I went with. I suppose the lower temp would suffice. My furnace goes to 2200 btw. Thanks for the heads up

Guess I should've said, none of us have a vacuum furnace. I'd never heard of this steel til now, what do you think of it? If you do some testing with it please share.
