The microstructure and property of the free cutting unquenched plastic die steels have been studied.
研究了易切削系非调质塑料模具钢的组织与性能。

The quenching strap is a bit higher than unquenched area, it is stressed by its neighborhood. This is beneficial to the wear resistance of quenched strap.
淬硬层略有浮凸，并受到来自未淬火的基体的挤压力，这对于提高硬化带的接触疲劳强度是有利的。

The grinding force ratio in grind-hardening consists with the grinding force ratio in grinding quenched steel, and is bigger than the grinding force ratio in grinding unquenched steel.
