Chemical Composition of H13 Mold Steel

　　H13 air quench hardening hot work die steel. THe properties and uses of H13 mold steel and 4Cr5MoSiV steel are basically the same. Due to H13 high vanadium content, the medium temperature (600 degrees) performance is better than 4Cr5MoSiV steel, is a representative steel number widely used in hot work die steel.

　　Chemical Composition of H13 Mold Steel (%):

　　Carbon C: 0.32 to 0.45;

　　Silicon: 0.80~1.20

　　Sulfur: ≤0.030

　　Phosphorus: ≤0.030;

　　Manganese: 0.20 to 0.50;

　　Vanadium: 0.80 to 1.20;

　　Molybdenum: 1.10~1.75

　　Chromium: 4.75 to 5.50;

　　Nickel: Allowable residual content ≤ 0.25

　　Copper: Allowable residual content ≤ 0.30;

　　Heat treatment: (Delivery status: Brinell hardness HBW10/3000 (less than or equal to 235)), quenching: 790 degrees + -15 degrees preheating, 1000 degrees (salt bath) or 1010 degrees (furnace controlled atmosphere) + -6 degrees heating , heat preservation 5~15min air cooling, 550 degrees + -6 degrees tempering; annealing, hot processing;

　　Delivery status: The steel is delivered in an annealed condition.
