How about that heat treat spray?

I have used foil on my knives forever. I had a friend in Sweden ask me why I used foil as I cold use spray instead and it does the same thing. I heat treat D2, the 154's and ATS. I am interested but just do not know. Any help?

He may be using Turco Pre-Treat, a spray on coating used in heat treating. K&G supplies has it in small quantities.

Okay, I will look into the Turco spray. But I just talked to my friend in Sweden who builds beautiful knives and he went through his heat treat and he does not use foil and does not understand why i do. His stuff is just fantastic and I just wonder the difference n heat treat methods.and do want to know more. Your thoughts?

Check the info on these things as they have temperature limits. For example they Turco may work on carbon steel but not on higher temps needed for stainless.

Turco has been used on carbon steels forever to protect the surface during hardening.

I doubt it will work on stainless. Too much time at high temp.

Yes, there's more than one of those coatings .Check the temperature range it's designed for.

Brownell's sells a anti scale coating that is called ATP-641. It can be sprayed or brush on prior to heat treating. the blade must be very clean from oils prior to coating. I use a cheap 1 inch foam rubber brush from the hardware store that cost about 50 cents. after use clean the brush with water.
I have only used it on 1095 so far and not on my S30V blades. The ATP-641 is rated by the maker of having a operating range of 1,000 to 2,300 degrees. I intend to test it on a scrap pieace of S-30V and see if it will hold up to the longer soak times at 1950. If it does, it will be far cheaper to use then stainless steel foil that is used for stainless steel blades.

Well I tried the ATP-641 on a scrap piece of S30V steel and put it in the kiln with two S30V blades that were wrapped in stainless foil. soak time was 25 minutes at 1950 degrees. the coating stayed on the steel. Upon cleaning ot up on the bader grinder, I noticed several small carbon pits in the blade. they were very small and only about 3 thousands deep and clean up very easy. I may try it again and apply one coat let it dry and then apply a second coat and see if that takes care of the minor pits.
The scrap piece of S30V tested for the same hardness as the two blades that were in the ss foil packet.
