H21 steel contains tungsten hot work die steel. This steel increases the Mo content by 2% and appropriately adds Mn content, which improves the high-temperature mechanical properties of the steel and adapts to the needs of mass production of aluminum alloy die-casting molds. This steel has high thermal elasticity, high thermal stability, good wear resistance and process performance, and the working temperature reaches 650℃。Our company provides alloy tool steel H21 round bar, hot rolled ASTM H21 mould steel plate etc.
