ENiCrMo-10 (Alloy C22)


Alloy Type:

ENiCrMo-10 Alloy C22 electrodes are used for the welding of nickel-chromium-molybdenum alloys as well as for overlay cladding on carbon, low alloy, or stainless steels.  They are also used for dissimilar joints between nickel-chromium-molybdenum alloys and stainless, carbon, or low alloy steels.  C22 offers excellent corrosion resistance in oxidizing as well as reducing media in a wide variety of chemical process environments.  It also offers spectacular resistance to stress corrosion cracking, pitting, and crevice corrosion.
