Abstract

In order to minimize the carbon content of an austenitic stainless steel weld deposited by an electrode having a basic flux coating and a low carbon austenitic stainless steel core, the coating includes at least 0.5% of one or more reactive oxides selected from the oxides of manganese, nickel, chromium iron and molybdenum or a corresponding amount of a salt of the oxide when the oxide is amphoteric. Specified salts are potassium chromate and potassium permanganate. The maximum carbon contents of the core wire and the deposit are 0.04% when the flux coating is free of columbium and 0.08% when the flux coating contains sufficient columbium to provide in the weld a columbium to carbon ratio of between 10:1 and 15:1. Examples of coating compositions for use on core wires having less than 0.04% carbon are: - .(1).15-60%.calcium, barium, magnesium or ...manganese carbonate ..15-60%.calcium, sodium or sodium alu- ...minium fluoride ..0-60%.powdered chromium, ferrochro- ...mium, nickel nickel-chromium, ...ferromolybdenu, ferrotitanium, ...ferrosilicon, ferromanganese or ...iron ..0.5-15%.oxide of nickel, chromium, man- ...ganese iron or molybdenum ..0-15%.oxide of titanium, silicon, alu- ...minium or zirconium ..0-3%.extrusion aid .(2).20%.chalk ..20%.fluorspar ..5%.felspar silica or bentonite ..13%.chromium ..15%.molybdenum ..12%.ferromolybdenum ..3%.iron ..6%.rutile ..4%.oxide of nickel or manganese ..2%.extrusion aid .(3).24%.chalk ..30%.fluorspar ..13%.chromium ..15%.molybdenum ..12%.ferromolybdenum ..1%.ferromanganese ..4%.manganese oxide ..1%.extrusion aid The core wire is 0.03% C, 19% Cr, 9% Ni, 1% Mn, 0.5% Si, balance iron and impurities.
