GEN 276 Overview
GEN 276 is used for welding of materials of similar chemical composition (UNS Number N10276), as well as dissimilar materials of nickel base alloys, steels and stainless steels. This wire also can be used for cladding steel with nickel-chromium-molybdenum weld metal. This alloy, due to its high molybdenum content, offers excellent resistance to stress corrosion cracking, pitting, and crevice corrosion.
