众所周知,高速钢通常都是用来制作刀具的。近年来,高速钢越来越广泛地用于模具制作,包括冷作模具和热作模具。但应注意,高速钢模具的热处理工艺,如淬火温度、保温时间等,与高速钢刀具是有区别的,特别是高速钢模具的淬火温度应适当降低一些,即采用低温淬火工艺,以确保模具有良好的韧性。有多个高速钢模具的热处理实例证明低温淬火对高速钢模具是行之有效的。
As we all know, high-speed steel is usually used to make tools. In recent years, high-speed steel is more and more widely used in mold making, including cold and hot die. However, it should be noted that high-speed steel mold heat treatment process, such as quenching temperature, holding time, and high-speed steel cutting tools are different, especially high-speed steel mold quenching temperature should be reduced, that is, using low-temperature quenching process to ensure that the mold Have good toughness. Several examples of heat treatment of high-speed steel molds prove that low-temperature quenching is effective for high-speed steel molds.
