日本日立SKH-9特种优质高速模具钢
SKH-9 日本日立YSS安来钢 属于冷模工具钢 又称YXM1 含钨量达5.5%以上
化学成份:
碳:0.8-0.9 硅:0.45以下 铬:3.8-4.5 锰:0.45以下 钼:4.5-5.5 钒:1.6-2.2 钨:5.5-6.7 磷:0.03 硫:0.01
钢材特性:
SKH-9高速钢W- MO系(6-5-2型)高速度工具钢最有普遍性,尤其是SKH9(SKH51)是在世界上用量很多,代替于W型高速度工具钢SKH2炭化物组织细微,整齐,分布良好。而且组织均匀。
所以耐磨性和革性方面比较均衡。
特别因为仅是炭含量上的增加或减少,因此不损坏高温特性,可连续且大幅度改变钢材性质。
需要革性时低炭素钢种适用,对硬度、耐磨性有要求的情况下适合选用高炭素钢钟。富有热作、冷作可塑性,被削性和研磨性也良好。
钢材一般用途:
此为钨钢高速度钢,宜于制造强力切割耐磨,高级蘅模,螺丝模,较需韧性及型状繁杂工具,铣刀、钻头等
出厂狀态及硬度(表面):HB900-1100/HRC63
SKH-9锻制工艺及特性: 锻造:1.100~900℃
退火:加热至800-850℃,在此温度中停留二~四小时,在炉中任其渐冷。
淬火:先预加热至550-600℃,次加热至950℃,再加热至a:1,220~1250℃;b: 1,200℃~1230℃。在油中淬硬,
但油温必须先保湿40-60℃(a.一般工具;b.形式复杂式需要韧性之工具)
回火:加热至550-570℃,在此温度中停留,然后在静止空气中冷却,回火必须重复二次 硬度:HRC63以上。
