AISI 904L Flanges

Flanges

AISI 904L Flanges are key connecting components, manufactured out of forged and plate 904L materials. Common types of AISI 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 AISI 904L flanges with welding neck, long welding neck, slip-on, socket-weld, screwed, tongue and groove, male and female type connection. AISI 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. AISI 904L plate flanges are manufactured to ASTM A240/A240M Type 904L (UNS N08904) material specification. AISI 904L pipe flanges are duly marked for traceability. We offer worldwide shipping by Sea or Air freight options.
