Development of New Type Special Steel in DaTong Co.,Japan

日本大同特钢公司开发的9种新型特钢,对提高我国钢铁产品附加值有意义。特别是Ni基耐高温腐蚀合金有高的耐V氧化物腐蚀性、超强韧钢的抗拉强度高达2080MPa、Fe基含Ni或含Cr、Ni系合金有高的加工硬化性,应力达到1700MPa、Co-W基超高耐热合金有多种优越的性能,有取代Ni基合金使用的趋势等。

It were related that 9 kinds of new type special steel(or alloy),which is meaningful to raise the additional value of steel product in China.Specially,Ni-based high temperature alloy has good resist of V-oxide corrosion,super-strong steel has strength of 2080MPa,Fe-based containing Ni or Cr and Ni alloy has good working-harden properties and its stress of 1700MPa,Co-W based alloy has good resist of high temperature which will can take the place of Ni based alloy in future.
