Cromamig 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.
– 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.
