C22 (ERNICRMO-10)

AWS A5.14 ERNiCrMo-10

ASME SFA 5.14 ERNiCrMo-10

Alloy C22® is a nickel chromium molybdenum alloy wire designed for joining Hastelloy® C22®, 625, 825 or combinations of these alloys, or other Ni-Cr-Mo alloys to themselves or to stainless steels. Washington Alloy C22® is equivalent to Hastelly® C22® and is also used extensively for overlays and cladding of lower alloy steels. Washington Alloy C22® weld deposits offer better overall resistance to weld metal corrosion than most other Ni-Cr-Mo alloys such as C276, C4 and 625. Washington Alloy C22® has outstanding resistance to pitting, crevice corrosion and stress-corrosion cracking. This alloy is used in chemical processing application involving ferric and cupric and inorganic, chlorine formic and acetic acids, acetic anhydride, sea water, and brine solutions.
