347 Stainless Steel Bar - 347 - National Specialty Alloys

347 stainless steel bar, also known as UNS S34700 and Grade 347, is an austenitic stainless steel made of.08% maximum carbon, 17% to 19% chromium, 2% maximum manganese, 9% to 13% nickel, 1% maximum silicon, traces of phosphorus and sulfur, 1% minimum to 10% maximum columbium and tantalum with the balance of iron.7 Things to Consider When Choosing a Stainless Steel Grade type 347 stainless steel chemical requirementsAug 22, 2016 · When welding austenitic stainless steels, grades such as 304L or 347 should be used. Grade 304L has lower carbon while 347 has niobium stabilizers added to it which help to deter intergranular corrosion. Ferritic stainless steels such as grade 430 or grade 439 are also readily weldable, as are Duplex stainless steels.Stainless Steel 347 - Alloy CompositionAlloy 347 has a slightly improved corrosion resistance over other alloys of stainless steel in strongly oxidizing environments as a result of the addition of columbium (niobium) and tantalum. Columbium-tantalum carbides precipitate within the grains instead of forming at the grain boundaries.
