一种新型高强韧热模具钢25Cr3Mo3VNo(HM_3),已由机械部北京机电研究所等单位共同协作研制成功。 HM_3钢不含镍钴,不同于国外近年来正在受到瞩目研究和应用的——性能比3Cr2W8V,958,HB等更高一级的——如苏联的含高钴的2XbB_8M2K8、2X_5B_5M_2K_5钢和其它国家的含高镍钴等元素的超高强韧热模具钢,也不同于国内近一、二十年来研究应用的中碳中合金型和基体钢型热模具钢。
A new type of high strength and toughness die steel 25Cr3Mo3VNo (HM_3), has been jointly developed by the Ministry of Machinery Beijing Institute of Electrical and other units jointly developed. HM_3 steel does not contain nickel and cobalt, unlike other foreign countries are undergoing research and application in recent years - higher performance than the 3Cr2W8V, 958, HB and so on - such as the Soviet Union containing cobalt 2XbB_8M2K8, 2X_5B_5M_2K_5 steel and other countries With high nickel and cobalt elements such as ultra-high toughness hot-die steel, but also different from the domestic one or two decades of research and application of medium-carbon alloy and base steel hot-die steel.
