由一机部机电研究所与本钢第一炼钢厂,长春第一汽车制造厂等单位协作研制成新型热模具钢5Cr4w5Mo2v。该钢种是以钨钼强化并加入能显著提高抗回火稳定性的元素,因而具有高热强性与热稳定性,是介于基体钢和高速钢之间的一个新钢种。冶金部曾将此钢种列为四个推荐使用热模钢种之一,目前本溪钢厂已正式供货。
Mechanical and electrical research institute by a machine with Benxi Iron and the first steelworks, Changchun Automobile Factory and other units to develop a new type of hot die steel 5Cr4w5Mo2v. The steel is based on tungsten and molybdenum and added to significantly improve the anti-tempering stability of the element, which has high thermal strength and thermal stability, is between the basic steel and high-speed steel between a new type of steel. Metallurgical Department has listed this steel as one of the four hot-rolled steel grades recommended, the current Benxi Steel has been officially available.
