摘要
本文研究的材料是为多工位冷挤压模具研制的模具材料。经多次反复的工艺性能和机械性能试验，找出成分最佳的模具材料，通过对比试验，其寿命比Ｃｒ＿（１２）ＭｏＶ钢提高１～２倍．
the material studied in this paper is applid to research and manufacture multipe workingorder cold extrusion moulding. Through manifold tests of techn ological and mechsnicslproperties. It is proved that its life increases 1～2 times comparing with Cr_(12)MoV.
