宝钢GW50钢结硬质合金钢_钢材硬度
GW50材料的特性
GW50钢是钢制的坚硬合金,还原碳高速钢由粉末冶金制成的铬钼合金钢,钢的粘附,WC是一个硬阶段。它的性能在钢和硬合金之间,可以通过淬火等热处理进行处理。因此,处理硬合金非常方便,并且比钢高得多。
钢具有良好的耐磨性和韧性较差,但比普通的硬合金更好。它可以执行机械处理。淬火几乎是非证明的,耐火性是良好的,并且深度的深度是深的。
由于脆皮,在锻造过程中通过多向应力锻造的方法更合适。在锻造中采用了两个光和一个重量的原理,锻造比可以>2。在自由锻造径向变形为6%-15%的过程中,类比期间火的轴向变形为15%-25% (在空白时采取下限,在锻造之后取上上限)。
冷压粗糙软化处理过程,使用高温加热,分割等效,然后与W18CR4V钢相同。
淬火状态的硬度为69-70HRC,弯曲强度为1700-2300 Quotempa,冲击韧性> 121/quotecm2。
