Material Properties 3 steel is nickel-chromium-free high-speed hammer mold steel. This steel has good melting, forging and heat treatment process properties. Due to the addition of nitrogen, the temper resistance of steel can be improved. This steel has good hardenability, has a gentle hardness gradient after quenching, and has excellent tempering resistance, but it is difficult to smelt, nitrogen is difficult to control, the cost is higher than 3 steel, and the toughness is poor
