MIG 312 deposits a 29% Cr / 9% Ni austenitic/ferritic stainless steel weld metal with a ferrite content of about FN 40. The weld metal exhibits excellent tolerance to dilution from dissimilar and difficult-to-weld base materials without hot cracking, together with high strength and very good heat and oxidation resistance. APPLICATIONS: – Difficult-to-weld steels e.g. high carbon hardenable tool, die and spring steels, 13% Mn steels, free-cutting steels, high temperature steels. – Dissimilar joints between stainless and high carbon steels. – Surfacing of metal-to-metal wear areas, hot working tools, furnace components. – Buffer layers prior to hard facing with high chromium carbide deposits.
