Stainless steel 316/ 316L flanges have enhanced resistance to pitting corrosion in chloride environments due to the addition of molybdenum. The letter “L” denotes low carbon content. According to ASME B16.5 and ASME B16.47, SS 316/ 316L flanges may be made from forgings of ASTM A182 Grade F316 or F316L, castings of ASTM A351 Grades CF8M or CF3M, and plates of ASTM A240 Grades 316 or 316L.
SS 316/ 316L flanges can be furnished in diverse types such as welding neck, slip on, blind, socket welding, lap joint, threaded, and reducing, etc. Flanges of ASME B16.5 may be provided in sizes 1/2″ through 24″ in Class 150, 300, 400, 600, 900, 1500, 2500. Flanges of ASME B16.47 Series A may be provided in sizes 26″through 60″in Class 150, 300, 400, 600, 900; while flanges of ASME B16.47 Series B may be provided in sizes 26″ through 60 in Class 75, 150, 300, 400, 600, 900
