粉末冶金法生产高速钢,从根本上解决了通常熔炼高速钢组织、成分上的偏析问题,改善了高速钢的性能;并为发展高性能的高合金高速钢开辟了一条极其重要的途径.世界上许多国家,尤其是工业发达的美、日、英等一些国家和公司,近年来投以巨资,争相研制,以多种粉末冶金高速钢及其刀具产品在国际市场出售.并使高性能高速钢品种增多,质量不断提高,粉末高速钢刀具制造工艺不断改进.瑞典联合出口钢铁公司(即《ASSAB)的乌德霍姆(U-ddeholm)公司生产粉末冶金高速钢的ASEA—STORA 方法是世界上先进的粉末冶金技术之一,其产品ASP23、ASP
Powder metallurgy method to produce high-speed steel, the fundamental solution to the general melting of high-speed steel microstructure, composition of the segregation problems and improve the performance of high-speed steel; and for the development of high-performance high-speed high-alloy steel has opened up an extremely important way. Many countries, especially the developed countries such as the United States, Japan and the United Kingdom, have invested heavily in recent years to develop and sell a large number of powder metallurgy high-speed steel and their knives in the international market, Performance High-speed steel grades increase in quality with ever-increasing improvements in the manufacturing process for high-speed powder steel knives ASEA-STORA method for the production of powder metallurgical high-speed steel from U-ddeholm, a Swedish export-export company (ASSAB) Is one of the world’s advanced powder metallurgy technology, its products ASP23, ASP
