The industry indicators of quenching castings

Castings

Castings are a class through a special processing of the workpiece. The hardening process is the important process of steel casting process, so what is the indicators of quenched steel casting process?

1.quenching medium. Hardened steel castings purpose fully grasp yo martensite. Castings cooling rate during quenching steel castings will require more than the critical cooling rate. Otherwise we can not get martensite and their corresponding properties.
2.quenching temperature. Quenching temperature is mainly determined the chemical composition of steel and the corresponding critical temperature point.
