40Cr Mold Steel

Has good comprehensive performance of mold steel

Performance:

What material is 40Cr? 40Cr is a medium carbon quenched and tempered steel. After appropriate heat treatment, this steel exhibits good hardness, plasticity, and wear resistance. After quenching and tempering, it possesses good comprehensive mechanical properties, good low-temperature impact toughness, and machinability. It is suitable for surface hardening treatments such as high-frequency quenching and flame hardening.
