Stainless Steel 304H Slip On Raised Flanges can be welded by all fusion and resistance welding processes. Stainless Steel 304H Blind Raised Flanges resists corrosion and is often used in the food industry. SS 304H Weld Neck Flanges has welded annealing only required in high stress applications. Stainless Steel 304L Threaded Flanges has excellent weld-ability characteristics with or without the addition of filler metals. Bending in Stainless Steel 304H Socket Weld Flanges will be responsible for distortions, upon the release of the piece from the clamping system. SS 304H Lap Joint Flanges has excellent corrosion resistance at normal temperatures in ordinary atmospheric conditions withstanding some natural acids. Cold work in these Stainless Steel 304H Ring Joint Type Flanges will cause an increase in both hardness and strength. Heavy welded sections in our SS 304H Orifice Flanges may require post-weld annealing. A post weld heat treatment in these Stainless Steel 304H Spectacle Blind Flanges is not necessary.
