Priminox Overseas is a known trader of Stainless Steel 317 / 317L Flanges, which is non-magnetic in nature. Stainless Steel 317 Slip On Flanges can be welded using fusion and resistance methods, where oxyacetylene welding method is not preferred for this alloy. Stainless Steel 317 Blind Spectacle Flanges is tougher than 304 stainless with a long stringy chip, where the use of chip breakers is recommended. In addition, annealing in Stainless Steel 317 Weld Neck Flanges can be performed on both grades between 1850 Degree F and 2050 Degree F, followed by rapid cooling. Stainless Steel 317 Orifice Flanges can be cold worked to various tempers and can be readily formed and drawn. Stainless Steel 317L Lap Joint Flanges is often used in chemical process equipment, petrochemical process equipment, pulp and paper manufacturing, condensers in fossil and nuclear fueled power generation stations. Stainless Steel 317L Flanges is also commonly used to handle sulfur, pulp liquor, acid dyestuffs, acetylating and nitrating mixtures, bleaching solutions, severe coal and oil, and many chemical compounds. Stainless Steel 317L Blind Raised Flanges should be heated to 1149 Degree C – 1260 Degree C (2100 Degree F – 2300 Degree F); however, it should not be heated below 927 Degree C (1700 Degree F). Increased levels of chromium, nickel and molybdenum in Stainless Steel 317L Ring Type Joint Flanges compared to 316L stainless steel improve resistance to chloride pitting and general corrosion.
