Keith Stainless Steel Heat Treat Foil is an annealed stainless steel used in the heat treating of tool steel parts. The wrap eliminates the need for Ni-Chrome, box packing and the use of sawdust or other carbonaceous materials. No special controlled atmosphere furnaces are required to use the foil.
Keith stocks stainless steel heat-treating foil with a .002" thickness in two grades of alloy and temperature ranges ready for immediate shipment to you. Alloy #321 is a high-titanium, soft annealed stainless intended for heat treating parts at temperatures up to 2000F. Alloy #309 may be used at temperatures up to 2240F.
