PM high speed steels(PMHSS) produced by the hot-isostatic pressing will have such merits as finer structure,segration-free,higher alloying element content,better workability and mechanical properties as well as wearability and so on,as compared with conventional high speed steels.
粉末冶金高速钢采用热等静压制工艺制作,与普通高速钢相比,具有组织细密,无偏析,合金元素含量高,可加工性好,力学性能和耐磨性好等优点。
