Alloy C-276
UNS N10276
Name：HASTELLOY C-276
C-276 is a kind of Nickel-Chromium-molybdenum alloy,including Wu, ex-low Si and C. It is generally regarded as all-proposed anticorrosive alloy. It has the following characteristics:
l Under oxidation and reduction circumstances ,it has excellent anticorrosive
property to most of corrosive media.
l Favorable resistance to pitting corrosion,slit corrosion and crack corrosion.
