Performance Characteristics:
It is a typical high-heat and high-strength mould steel. The main alloying element W content up to 8% or more,this kind of steel has high hardness and high strength after heat treatment.
Applications:
1.High ability of anti-tempering ,it is used to make high stress but no shock loading male mold and female mold.
2.Bending stressor tensile stress mould such as anti-extruding die.
3.Cuttting tool in high temperature stress.
