H21 Mold Steel/Mould Steel die steel commonly used die casting die steel has high strength and hardness, good resistance to cold and heat fatigue, and good hardenability, but its toughness and plasticity are better. This steel contains more carbide forming elements chromium, tungsten, vanadium, the phase change temperature increases, so that the steel has high high temperature strength, hardness and good heat resistance fatigue.

Product Advantage
The main features of H21 hot work Mold Steel/Mould Steel die steel include:
High hardness: H21 hot work die steel has extremely high hardness, which can be further improved by heat treatment and maintain good cutting performance.
Excellent wear resistance: H21 hot work die steel has excellent wear resistance after proper heat treatment and can be used to process molds of high hardness materials.
Good heat resistance: H21 hot work die steel maintains high hardness and strength in high temperature environment, and can resist deformation and fatigue damage at high temperature.
Excellent inch stability: H21 hot work die steel has a low coefficient of thermal expansion, so that the mold can still maintain accurate dimensional stability at high temperatures.
