Our stainless steel 316 socket weld flanges can be easily welded and machined through standard shop fabrication practices. For most hot working processes, these stainless steel 316L lap joint flanges are recommended for forming at 1700¡ãF – 2200¡ãF (927¡ã – 1204¡ãC) Our stainless steel 316 ring joint style flanges are very ductile and easy to Forming, work hardening occurs during deformation, and chip breaking is easy.
Cold working operations will increase the strength and hardness of these stainless steel 316L eyeglass blind flanges and may make them slightly magnetic. Flanges are usually welded or threaded. Flange joints are made by bolting two flanges together with a gasket between them to provide a seal.
SS 316/316L flanges can be fabricated from ASTM A182 F316 or F316L forgings, ASTM A351 CF8M or CF3M castings, and ASTM A240 316 or 316L plates per ASME B16.5 and ASME B16.47.
SS 316/ 316L flanges are available in many types such as butt weld, socket, blind hole, socket weld, lap, thread and reducer.
ASME B16.5 flanges are available in sizes 1/2″ to 24″ in classes 150, 300, 400, 600, 900, 1500, 2500.
ASME B16.47 Series A flanges are available in sizes 26″ to 60″ in 150, 300, 400, 600, 900 classes; while ASME B16.47 Series B flanges are available in 75, 150, 300, 400, 26″ to 60 sizes in 600, 900 grades.
Stainless steel 316/ 316L flanges can be made by hot forging or casting. Blind or sliding plate flanges without hubs can be machined directly from the plate. Flanges should be solution treated at not less than 1900¡ãF [1040¡ãC] and then quenched in cold water or other rapid cooling method.
These stainless steel 316L threaded flanges perform well in fresh water service even with high chloride levels.
In most cases, the corrosion resistance of our stainless steel 316 butt weld flanges is about the same in most corrosive environments.
In environments that are corrosive enough to cause intergranular corrosion in welds and heat affected zones, these should use stainless steel UNS S31600/S31603 blind flanges due to its low carbon content.
