ASTM A182 316L spacer ring SS UNS S31603 Slip On Flanges
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.
Both chemical composition and mechanical properties are required to meet ASTM A182 specifications. Speaking of its chemical composition, the alloy used to produce UNS S31600 SS 316L flanges contains a lot of nitrogen. A182 F316L Plate Flanges are part of the A182 specification, which specifies forged or rolled flanges, fittings, valves and other components for high temperature service.
