Product Basic Information:
Chemical component
C0.30~0.40 Si≤0.40Mn≤0.40Cr2.20~2.70W7.50~9.00V0.20~0.50p≤0.030S≤0.030
H21 is Tungsten hot die steel.The high temperature mechanical properties of the steel are improved by increasing the content of Mo to 2% and adding the content of Mn appropriately, , which is suitable for mass production of aluminum alloy die casting.The steel has high thermal elasticity, high thermal stability, good wear resistance and process performance, and the working temperature reaches 650℃
