ITC Ceramic Coatings now in stock at Canadian-artisan along with Condursal Z1100 Satanite Refractory ATP-641 There is a new product in development that will be used as a anti-carburizing coating when heat treating. I am testing a sample for use on stainless steels and if results are positive the developer may request further trials or testers. Use in Forges for forge welding and heat treating Professional heat treaters
When working with stainless steels then "Condursal Z1100" will replace foil wrap. Condursal has two critical temperatures you have to work within and the lower temperature is usually the one that trips up new users when the coating burns off. If working with typical high carbon steels then ATP-641 will do a good job and be less expensive in the long run. It also has a minimum temperature that is best not to go below.
@John Noon John, what I am hearing on the Condursal is either comes off easy after or sticks like to a blanket
What happens to get problems 1- lack of proper coverage 2- ignoring minimum safe temperature. You can tell when the coating is thin by the lighter color. Second is to program a step in the furnace above 600C I did run into a third problem myself and that was a drilling fluid that fought all cleaning attempts. When this happens any coating that follows has an above average grip
John, will atp 641 be fine for stainless steel? The Max temp is rated at 2400f so I would assume there wouldn’t be an issue. Or is condursal better for stainless? I do a majority of my grinding post heat treating so if there’s some surface decarb it doesn’t bother me too much.
