Stainless steel foil tool wrap protects air hardening tool steel parts from scale and oxide buildup during heat treating in ordinary furnaces. By using foil tool wrap in your conventional furnace, you will realize nearly the same benefits of vacuum or controlled atmosphere furnaces but at a fraction of the cost.

Heat Treating Foil

Foil may be cut, folded, and creased easily to create a protective airtight envelope

around your parts that will not tear easily during normal use. Our high quality foil is produced by mills here in the U.S. to exacting metallurgical standards and with a very uniform thickness. The foil is resistant to chromium carbide precipitation during exposure to high temperatures. Decarburization buildup is also eliminated.
