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.
