摘要
分析了预硬型大截面塑料模具钢Ｐ２０ＢＳＣａ的合金化特点，并对热处理工艺进行了研究．结果表明，该钢具有优良的热处理工艺性能及预硬性能，淬火温度区间宽，适当地调整回火温度，可以很方便地得到ＨＲＣ３０～４５的预硬硬度要求；
Alloying feature and heat treatment procession of prehardening plastic mould steel P20BSCa were studied. The results show that the steel has excellent heat treatment and prehardening properties. Quenching temperature range is 820- 900℃, It is easy to have the required hardness by adjusting the temper temperature. Other heat treatment parameters were suggested.
