Heat Treat Safely Without Scale

Saves hours of polishing, grinding, shaping - parts can be made to exact dimensions before heat treating without fear of dimension change from scaling, pitting, decarb loss. Extremely simple to use - for both hardening or annealing. Heat the work piece to about 500° F., coat with the dry compound powder, finish heating to temperature, and quench/cool as required. Parts come clean in boiling water.
