904L Flat Flange is simple flat loose flange, used for low pressure piping connection. Anand Steels offers 904l Flat flanges for 1/2 to 80” nominal pipe sizes. These flanges are directly machined from 904l Flats with further drilling of bolt holes and centre bore. We can manufacture flat lap joint, blind, slip on, socket weld and threaded flanges from Flat material. These flanges are quickly produced as compared to forged flanges. Blinds are most commonly produced Flat flange. We offer raised face and flat face with desired serration roughness for leak proof joint.

ASTM A240 / ASME SA240 is the material specification referred to 904l Flat flanges. We supply these 904l stainless steel Flat flanges with plastic caps for protection from dust and physical damages.
