用超硬高速钢材料制造模具

Die Making with Super-hard High Speed Steel

应用和推广模具新钢种,是不断提高模具性能,延长模具使用寿命的重要途径。V3N钢材是一种超硬高速钢,通常用于制造金属切削刀具。通过对其基本化学成分、力学参数和工艺性能的分析,可知它具有硬度高、耐磨性好和高的红硬性,而且价格便宜、切削性能好,磨削和热处理是加工中的关键工序。与其它模具钢比较,V3N钢有着突出的优势和特点。可以取代目前常用的传统模具钢材,用于制造要求耐磨、高硬的模具零件,达到模具寿命长、经济效益好的目的。

Using and promoting new die steel is the important way to unceasingly enhance the die performance and lengthen the die service life. The steel V3N is a kind of super - hard high speed steel, usually is used in making metalworking tools. Through analysis on its basic chemical composition, mechanics parameter and technology performance, find the features of high degree of hardness, good wear resistance and high red hardness, as well as low price and good cutting performance. Grinding and heat -treatment are the key processes. Comparing with other die steels, the steel V3N has outstanding advantages and characteristics. It can be used in making wear resistant and high hardness dies instead of traditional die steels, reaching the aims of long life and good economy.
