在大量或批量生产中,高速钢,特别是P6M5钢被广泛地用于制造各种冷冲压工具。当工具的工作应力很高时(达22兆帕),例如,冷镦中碳钢和低合金时(如35、40Х、38ХГНМ等),采用这类钢是有效的。这是因为,经淬火和多次高温回火后,在高速钢组织中几乎不存在能明显地降低接触强度的残余奥氏体。利用低合金的8Х4В2С2МФ(ЗП761)、6Х4М2С(ДИ55)钢的弥散硬化,不可能达到P8M5钢那样的综合性能,
In mass or mass production, high-speed steels, particularly P6M5 steels, are widely used to make a variety of cold stamping tools. The use of such steels is effective when the working stress of the tool is high (up to 22 MPa), for example when cold forging medium carbon steel and low alloy (eg 35,40Х, 38ХГНМ, etc.). This is because, after quenching and high temperature tempering, there is almost no residual austenite in the high-speed steel structure that can significantly reduce the contact strength. The use of low alloy 8Х4В2С2МФ (ЗП761), 6Х4М2С (ДИ55) steel dispersion hardening, P8M5 steel can not achieve the same overall performance,
