Cold forging & heat treatment - Cold forging and heat treatment greatly improve the performance of the socket with enhanced hardness, increased wear-resistance and lifespan. Cr-mo alloy steel - cr-mo impact socket features with added strength, higher working temperatures and corrosion resistance. Black phosphating - A fine and dense coating brings more corrosion and wear resistance for longtime use. It’s much stronger to stand greater impact force than chrome vanadium ones.
