Cobalt Alloy Stellite 6 UNS R3006
\
相似牌号：Stellit 6; UNS R3006; AMS 5387C-2001
介绍：
是一种钴基合金，用于磨损环境，防咬死，防磨损，防摩擦。合金6B的摩擦系数很低，能和其他金属产生滑触，在多数情况下不会产生磨损。即使不用润滑剂，或者不能用润滑剂的应用中，6B合金可以把咬死和磨损降至最低。合金6B的耐磨性能是与生俱来的,不依靠冷作加工或热处理,因此也能减少热处理工作量和后续加工的成本。合金6B耐受气蚀, 耐冲击,耐热冲击和多种腐蚀介质， 在赤热状态下,合金6B能保持很高的硬度(冷却后可以恢复原来的硬度). 在既有磨损又有腐蚀的环境中, 合金6B非常实用.合金6B可用于制造阀门零件,泵柱塞,蒸汽机防腐蚀罩,高温轴承,阀杆,食品加工设备,针阀,热挤模具,成型磨具等。
