H13 hot work mold steel is under GB/T1299 standard. H13 material is an alloy die steel used to manufacture forging die with large impact load, hot extrusion die, and precision forging die. Due to its excellent combination of high toughness and fatigue resistance H13 is used more than any other tool steel in tooling applications.
H13 die steel equivalent is 4Cr5MoSiV material. The main features of high alloyed Cr-Mo-V hot work die steel is high wear resistance to thermal shock and to heat cracking, good mechanical characteristics & toughness in hot condition. H13 steel appears excellent machinability with constant hardness during production activities.
