Ni-112
AWS/SFA5.11 Class ENiCrMo-3 W86112
Washington Alloy 112 is a nickel chromiummolybdenum
flux-coated electrode designed for shielded metal-arc welding of lnconel® 625 or 601, for high strength welds on 9% nickel steels and for overlaying carbon steel. Washington Alloy 112 is also used for joining dissimilar combinations of
steels or stainless steels to nickel-iron-chromium alloys such as lncoloy® 800 or 801.
APPLICATIONS
More common uses of Washington Alloy 112 include the nuclear industry where it is used for pressure vessel superheaters, steam separators and tube plates. This electrode is commonly used in cryogenic installations; chemical and petrochemical applications; and for heat treatment and case hardening indus¬trial furnace parts. More specific uses include joining Inconel® 625, 718, X-750 and 706 to 9% nickel steels; for welding Incoloy® 825 to carbon steel, stainless steel and low alloy steel; for joining Inconel® 625, Monel® K-500, Incoloy® 800 and 825 to Inconel® 706, 718 and X-750; and for joining Incoloy® 825 and 800.
