Factory Worker Puts Hot Pieces Of Metal In A Container Of Boiling Oil For Hardening.
Factory worker puts hot pieces of metal in a container of boiling oil for hardening. Annealing is achievement of high hardness, strength, and hence wear resistance of steel. Formed non-equilibrium structure requires a subsequent tempering. When oil quenching product formed is much less thermal cracking than when quenching in water. This oil is used as working medium in heat treatment of metals. Allow to obtain steel products with specified hardness values, required structure and clean surface.
