Abratig C22
Description & applications
HASTELLOY® C-22® RTW™ Filler Metal is used for 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-chromiummolybdenum alloys and stainless, carbon, or low alloyed steels.
Typical specifications for the nickelchromium- molybdenum base metals are ASTM, F574, B619, B622 and B626. All of which have UNS Number N06022.
It offers excellent corrosion resistance in oxidizing as well as reducing media in a wide variety of chemical process environments. It offers an outstanding resistance to stress corrosion cracking, pitting and crevice corrosion.
UNS: W86022
Welding of Inconel alloys 622 and 625, alloy 25-6Mo, and Incoloy 825
Also recommended for joining molybdenum-containing stainless steels, low alloyed steels, Hastelloy C4, C22, C-276 and Inconel 625, 2.4611
