推广国产优质SRM-1模具钢应用促进铝挤压工业与技术发展

Expanding applications of domestic SRM-1 mold steel to develop aluminum extrusion industry and technology

模具材料是决定铝挤压模具使用寿命、提高产品质量的关键要素。较全面地介绍了国产的高性能、长寿命优质铝挤压模具特种合金钢SRM-1的性能与用途,并与国外先进的模具材料(如H13、1.2344、SKD61、H21等钢材)进行了对比分析。结果表明,国产SRM-1钢的各种性能达到或优于国外同类先进钢材的,模具使用寿命也大大提高,而且价格低廉,性价比高,可大大降低生产成本,从而促进我国铝挤压工业的发展。

Mold materials are crucial to service life of aluminum extrusion molds and prod- uct quality extruded by the molds. Special alloy steel SRM-1 is one of the domestic materials that can bring aluminum extrusion molds with good performance, long life, and sound quality. SRM-1 has been introduced on its performance and applications. Compared with the ad- vanced mold materials in the other countries（ e. g. H13,1. 234 4, SKD61 and H12）, SRM-1 is at the same level or even better with longer life, lower prices and higher price-quality ratio. It can reduce production cost greatly, as a way to develop domestic aluminum extrusion indus- try.
