Nickel Alloy C22 (ERNiCrMo-10) is used for
welding materials of similar chemical composition
as well as dissimilar joints between nickelchrome-
molybdenum alloys and stainless or
carbon or low alloy steels. The high molybdenum
content provides great resistance to stress corrosion
cracking, pitting, and crevice corrosion.
This alloy is suitable for a variety of chemical
process environments.
