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 500deg F., coat with the dry compound powder, finish heating to temperature, and quench/cool as required. Parts come clean in boiling water. Mfg: Brownells SPECS: 1 lb. (454 g). Not for steels that harden above 1650deg F.
