Alpha Overseas(AOS) manufactures and exports these SS 347 Socket Weld Flanges, where columbium-tantalum carbides precipitate within the grains instead of forming at the grain boundaries. These Alloy 347 Flanges offers higher creep and stress-rupture properties than Alloy 304 and, particularly, Alloy 304L, which might also be considered for exposures where sensitization and intergranular corrosion are concerns. However, the hardenability of our Grade 347 Lap Joint Flanges can be minimized by the use of constant positive feeds and slow speeds. These Type 347 Flanges is often used in aircraft collector rings, exhaust manifolds, chemical production equipment, etc. AISI 347 Flanges are also advantageous for high temperature service because of their good mechanical properties, which further demonstrates improved high temperature and creep properties. The high temperature oxidation resistance of these 347 Stainless Steel Weld Neck Flanges is similar to that of stainless steel 304, which is further useful to 1500 Degree F. Stainless Steel 347 Slip On Flanges is used for welding types, and so it is used in steam or utility applications up to 760 Degree C. These Stainless Steel 347 Blind Flanges cannot be hardened through heat treating, but elevated properties may be obtained through cold reduction.
