skh51怎么降低硬度

　　Cu≤0.25

　　高红热硬度、高耐磨耗性与切削能力、高冲击韧性、晶粒细致均匀，韧性高。SKH-51模具钢材为钨钢高速度钢，宜于制造强力切割用耐磨，耐冲击各种工具，高级冲模，螺丝模，较需韧性及形状繁杂工具，铣刀，钻头等。

　　①W-MO系（6-5-2型）高速度工具钢最有普遍性，尤其是SKH51是在世界上用量很多，代替于W型高速度工具钢SKH2.

　　②碳化物组织细微，整齐，分布良好。而且组织均匀。所以耐磨性和韧性方面比较均衡。特别因为仅是碳含量上的增加或减少skh51怎么降低硬度 ，因此不损坏高温特性skh51怎么降低硬度，可连续且大幅度改变钢材性质。需要韧性时低碳素钢种适用，对硬度、耐磨性有要求的情况下适合选用高碳素钢钟。
批发skh51高速钢

　　skh40模具钢对比skh51模具钢有什么区别？skh51模具钢又名风钢或锋钢，意思是淬火时即使在空气中冷却也能硬化，并且很锋利。它是一种成分复杂的合金钢，含有钨、钼、铬、钒、钴等碳化物形成元素。合金元素总量达10～25%左右。它在高速切削产生高热情况下(约500℃)仍能保持高的硬度，HRC能在60以上批发skh51高速钢。这就是高速钢主要的特性红硬性批发skh51高速钢。而碳素工具钢经淬火和低温回火后，在室温下虽有很高的硬度，但当温度高于200℃时批发skh51高速钢，硬度便急剧下降，在500℃硬度已降到与退火状态相似的程度，完全丧失了切削金属的能力，这就限制了碳素工具钢制作切削工具用。而高速钢由于红硬性好，弥补了碳素工具钢的致命缺点，可以用来制造切削工具。
