Hastelloy Series
Ni-Mo and Ni-Cr-Mo alloys engineered for the most aggressive wet-corrosion environments, from hydrochloric acid to oxidizing chloride media.
Where This Series Fits
- B 系列为镍钼基，专攻盐酸等还原性酸；C 系列为镍铬钼（部分含钨），兼顾氧化性与还原性介质
- Hastelloy C-276 是通用耐蚀牌号，广泛用于化工、烟气脱硫与污染控制设备
- Hastelloy C-4 抑制焊接与高温暴露下的晶界析出，可焊态直接使用
- Hastelloy X 转向高温抗氧化，用于 1000°C 以上的燃烧室与工业炉部件
