SS 904L Flanges
SS 904L Flanges are key connecting components, manufactured out of forged and plate 904L materials. Common types of SS 904l flanges includes welding neck, long weld neck, slip-on, socket-weld, screwed or threaded, blind, lap joint, plate, orifice, spectacle and other custom types.
Anand Steels manufactures and supplies SS 904L flanges with welding neck, long welding neck, slip-on, socket-weld, screwed, tongue and groove, male and female type connection. SS 904L flanges are manufactured to ASTM A182 F904L forged material specification and ANSI/ASME B16.5, B16.36, B16.47 Series A, Series B, B16.48, BS 10, BS 1560, EN 1092-1, API 6A, 6B, 6BX, ISO, GOST and various DIN standards. SS 904L plate flanges are manufactured to ASTM A240/A240M Type 904L (UNS N08904) material specification. SS 904l pipe flanges are duly marked for traceability. We offer worldwide shipping by Sea or Air freight options.
