These Stainless Steel 347H Orifice Flanges offers good resistance to polythionic acid stress corrosion cracking, encountered in oil refineries. The use of slow speeds and constant positive feeds will minimize the tendency of our SS 347 Threaded Flanges to work harden. These Stainless Steel 347H Socket Weld Flanges should be considered for applications requiring intermittent heating between 800 Degree F (427 Degree C) and 1650 Degree F (899 Degree C), or for welding under conditions which prevent a post-weld anneal. Our Stainless Steel 347 Weld Neck Flanges is columbium stabilized austenitic stainless steel plate with good general corrosion resistance and somewhat better resistance in strong oxidizing conditions than 321. Other applications where these SS 347H Blind Raised Flanges are chosen are boilers, jet engine parts, exhaust manifolds, mufflers for large engines and other various welded parts.

Steel 347 Flanges

SS 347H Flanges

Applications that consistently used our Stainless Steel 347 Slip On Raised Flanges include: Heavy duty exhaust systems, High temperature chemical processes, General refinery piping, Heat exchanger tubes, High pressure steam pipes, High temperature steam service, Radiant superheaters, and so on. The additions of these elements in these SS 347H Weld Neck Flanges promote improved inter-granular corrosion resistance. The addition of columbium produces a stabilized type of Stainless Steel 347 Flangesthat eliminates carbide precipitation, and consequently, intergranular corrosion. We are a known dealer of SS 347 / 347H Flanges, which is weldable by common fusion and resistance methods.
