Abstract: A ferritic stainless steel weld wire for forming a ferritic weld deposit free of martensite under a gas blanket containing a reactive component. The weld wire contains in weight percent about______________________________________ w/o ______________________________________ Carbon 0.04 maximum Manganese 1.0 maximum Silicon 1.0 maximum Phosphorous 0.045 maximum Sulfur 0.045 maximum Chromium 10.50-12.00 Titanium 0.30-0.75 Nitrogen 0.02 maximum Nickel 0.25 maximum Molybdenum 0.50 maximum Copper 0.50 maximum Cobalt 0.25 maximum ______________________________________and the balance iron. The ratio of the weight percent titanium to the sum of the weight percent carbon plus the weight percent nitrogen is at least 12.5:1 in the weld wire and at least 8:1 in the weld deposit.

Abstract: weld-filler material particularly useful in providing enhanced freedom from weld cracking in fully austenitic Fe--Ni--Cr--Mo--Cu material in which the elements P, Cb, Ce+La, C, Si, S, N and O are controlled to low levels and in which the level of manganese is increased to at least 1% and preferably to at least 1.5%. The weld-filler material in weight percent contains:Carbon -- 0.035 Max.Manganese -- 1-4.0Silicon -- 0.20 Max.Phosphorus -- 0.020 Max.Sulfur -- 0.005 Max.Chromium -- 19.0 -26.0Nickel -- 32.5-38Molybdenum -- 2-9Copper -- 3.0-4.0Columbium -- 0.35 Max.Cerium -- 0.01 Max.Boron -- 0.0035 Max.the balance being iron and in which cerium includes cerium plus lanthanum or misch metal.
