9SiCr Alloy Steel
9SiCr steel has good forging properties. Because it is easy to decarburize, 9SiCr steel needs to be heated in a neutral atmosphere or protective atmosphere furnace. By applying forging heat quenching and tempering treatment, a fine tempered sorbite structure can be obtained, which simplifies the process, saves time and energy, and has both good cutting performance and ideal waste heat treatment structure.The corresponding trademark of 9SiCr steel in other countries is DIN 1.2067、DIN 100Cr6、L3 steel.

AISI H21 Hot Work Tool Steel
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.
