Nickel Alloy C276 (ERNiCrMo-4) is used
for welding materials of similar chemical
composition (UNS Number N10276) as
well as dissimilar materials of nickel base alloys,
steels and stainless steels. This alloy can also
be used for cladding steel with nickel-chromemolybdenum
weld metal. The higher
molybdenum content provides great
resistance to stress corrosion cracking,
pitting, and crevice corrosion.
