Citizen Metals is a prominent leader in trading, supplying and distributing a wide range of SS 904L Flanges, which is a non-stabilized austenitic stainless steel with low carbon content. Stainless Steel 904L Slip On Flanges is widely used in applications where the corrosion properties of Stainless Steel 316L and Stainless Steel 317L are not adequate. These Stainless Steel 904L Blind Flanges is a fully austenitic low-carbon variety of stainless steel with additives of molybdenum and copper. Stainless Steel 904L Spectacle Blind Flanges is a super-austenitic stainless steel designed for corrosion and pitting resistance in a wide range of process environments. The low carbon content of these Stainless Steel 904L Socket Weld Flanges improves cleanliness and weld strength. The addition of copper to Stainless Steel 904L Weld Neck Flanges gives it greatly improved resistance to strong reducing acids, particularly sulphuric acid.
These Stainless Steel 904L Threaded Flanges has high resistance to crevice and stress corrosion cracking. Stainless Steel 904L Lap Joint Flanges is intended for use under severe corrosive conditions. These Stainless Steel 904L Ring Type Joint Flanges is commonly used in chemical and petrochemical industry for handling medium concentrated sulphuric acid. Our Stainless Steel 904L Orifice Flanges has a very good resistance to attacks in acidic environment, as sulphuric, phosphoric and acetic acid. These Stainless Steel 904L Tongue & Groove Flanges is a suitable austenitic stainless steel to be used in the prevention of hot seawater corrosion and chloride based attack.
