What is material 30CrMo equivalent steel grade

What is material 30CrMo equivalent steel grade

The material 30CrMo is a Chinese alloy steel for engineering and machine structural use. The material 30CrMo has high strength, high toughness, and it has good high temperature strength at temperatures below 500℃. The well known material 30CrMo equivalent steel grade is AISI 4130.

The material 30CrMo chemical composition:

Grade C Si Mn Cr Mo Ni W B Al Ti V
30CrMo 0.26-0.34 0.17-0.37 0.40-0.70 0.80-1.10 0.15-0.25            

30CrMo equivalent steel AISI 4130 has close chemical composition to material 30CrMo. The material 30CrMo and its equivalent AISI 4130 steel has good machinability, medium cold bending and plasticity, high hardenability as well as good weldability. They have high durability and creep strength at high temperature, and they also have good low temperature impact toughness.
