347 sheet stainless steel is a columbium/tantalum stabilized austenitic chromium-nickel stainless steel. Type 347 sheet has excellent intergranular corrosion resistance and oxidation resistance. at high temperatures. This material is stabilized against chromium carbide formation by the addition of columbium and tantalum. Since these elements have a stronger affinity for carbon than chromium, columbium-tantalum carbides precipitate within the grains instead of forming at the grain boundaries. 347 sheet should be considered for applications requiring intermittent heating between 800ºF (427ºC) and 1650ºF (899ºC) or for welding under conditions which prevent a post-weld anneal. 347 is non-magnetic.

Stainless Steel 347  Sheets precipitates and coagulates the carbides and results in large ferrite crystals. Cold – formed steel is usually annealed and recrystallized in this manner, holding 347 Sheet for several hours at about 680 Degree C (1,260 Degree F). Then, during cooling, a very uniform grain is formed in 347 Sheet Coils, consisting of either pearlite and ferrite or pearlite and cementite, depending on carbon content. In a different system, the cold – rolled strip in SS 347 Sheets is pulled through high furnace with the strip moving up and down between many top and bottom rolls. Before cold forming, hot – rolled SS 347 sheet Plates is always descaled, most commonly in an operation known as pickling.
