Alloy C276

ALLOY C276 | UNS N10276

Description

Alloy C276 is a nickel-molybdenum-chromium alloy with an addition of tungsten designed to have excellent corrosion resistance. The high nickel and molybdenum contents make the nickel steel alloy resistant to pitting and crevice corrosion in reducing environments while chromium conveys resistance to oxidizing media.
