20CrMnM0

20CrMnM0

High-level penetration of high-strength steel, plastic and slightly lower toughness, after quenching and tempering has good mechanical properties and low temperature impact toughness after quenching carburizing high bending strength and wear resistance, resistance is not before welding Well, to be heated before welding, after welding to be tempered, machinability and hot workability is good.
Main Uses Commonly used in the manufacture of high hardness, high strength, high toughness, large pieces of important carburizing.
