摘　　要：概述了国外粉末冶金工模具钢的种类及特性。指出了我国在粉末冶金工模具钢方面与发达国家的差距。展示了粉末冶金工模具钢在我国的应用前景。强调我国作为钢铁大国必须拥有自己的粉末冶金钢技术,利用我国丰富的钨资源开发出具有知识产权的粉末冶金工模具钢。The sorts and properties of powder metallurgy tool and die steels abroad were summarized. The deficiencies were indicated in powder metallurgy tool and die steels in China compared with the developed countries. The application of powder metallurgy tool and die steels at home were also forecasted. In particular, for China as one of the major steel countries, it is absolutely necessary to possess new technologies of powder metallurgy steel and to develop the patents of powder metallurgy tool and die steels with intellectual property by making full use of abundant tungsten resource.
