ASTM B622 HASTELLOY C276(UNS N10276/DIN 2.4819) NICKEL ALLOY STEEL PIPE/TUBE
哈氏合金 C276 is a nickel-molybdenum-chromium super alloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments. The high nickel and molybdenum contents make the nickel steel alloy especially resistant to pitting and crevice corrosion in reducing environments while chromium conveys resistance to oxidizing media. The low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures. This nickel alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone， thus making it suitable for most chemical process application in an as welded condition.
