    Or just use a thin coat of satinite.

    ATP 641 anti-scale compound is available through the manufacturer: Advanced Technical Products
    Go to website, shoot them an email...Brownells is not the only outlet, buy it directly from manufacturer.
    $51/quart + shipping.
    I ordered through Brownells, FedEx lost my order, major hassle. ATP ships UPS, hoping it arrives.

    I have yet to use this, hoping to HT some O1 soon. Also have SS blank about ready for hardening, definitely need anti-scale/ refractory cement for this.
    Wish me luck!
    Brand New maker here....

    My thoughts are that with stainless streel temperatures and soak times you have to use a stainless foil packet. Blade coatings work fine for carbon steel.

    What some of these heat treat compounds do to a blade at the temps for SS austenitizing is truly amazing. Eats holes into it all over. Borate gets really intensely corrosive at SS temps. Glad it was a test blade, unground, and available for sacrifice.

    Yeah, I made that mistake many years ago. I put Turco-II on a stainless blade and did HT. It ate the blade up. Borax and similar compounds turn really corrosive above 1700°F.

    You mentioned this in your first post .........the ability to see the color changes in the steel?
    Does that means that you will use forge for HT ?
    You will really need luck if you HT stainless in forge
