ASP 钢是国外发展的一种新型粉末冶金高速钢,它是采用最先进的粉末冶金等静压实工艺制造的。因此,它具有碳化物组织分布均匀、韧性与耐磨性都此普通冶炼方法制造的高速钢较好等优点。粉末冶金高速钢最初只是用于制作切削难加工材料的刀具和高速切削刀具,而最近已发展到用于制作冷加工模具。本文结合 ASP steel is a new type of powder metallurgy high-speed steel developed abroad, which is manufactured using the most advanced powder metallurgy isostatic compaction process. Therefore, it has the advantages of even distribution of carbides, high toughness and wear resistance of high-speed steel produced by this common smelting method. Powder metallurgical high-speed steel was originally only used to make cutting difficult materials and high-speed cutting tool cutting tools, and has recently been developed for the manufacture of cold-working mold.
