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.
