6. Hardenability
After quenching, a deep hardened layer can be obtained, which can be hardened with a mild quenching medium.
7. Quenching deformation cracking tendency
The conventional quenching volume change is small, the shape is warped, the distortion is slight, and the abnormal deformation tendency is low. Conventional quench cracking has low sensitivity and is not sensitive to quenching temperature and workpiece shape.
8. Grindability
The relative loss of the grinding wheel is small, the maximum amount of grinding without the burn is large, and it is not sensitive to the quality of the grinding wheel and the cooling condition, and it is not easy to cause abrasion and grinding crack.
