Vacuum Degassing Sncm220 Alloy Material Performance Characteristics - China

The carburizing and quenching process of SNCM220 alloy material can effectively improve the surface hardness and wear resistance, while ensuring the toughness of the core, making it widely used in high-strength wear-resistant parts such as gears and shafts.

Pretreatment (refining production)

In the process of steel plate production, the electric furnace + LF refining + VD vacuum degassing process is used to reduce the inclusion content in the steel and improve the purity.

Control the content of elements such as C, Mn, Si, Cr, Mo, Ni in the steel to meet the SNCM220 standard (JIS G4053) Performance characteristics of SNCM220 alloy material after carburizing and quenching

Surface hardness: HRC 58-62

Core hardness: HRC 30-45 (maintain toughness)

Wear resistance: significantly improved, suitable for high-load wear-resistant parts

Fatigue resistance: the carburized layer matches the good toughness of the core to improve impact resistance SONGSHUN
