Seamless Stainless 904L Pipes and Tubes

SILVER TUBES offer stainless steel 904L tubes which is a low carbon high alloy austenitic stainless steel which is widely used in applications where the corrosion properties of AISI 316L and AISI 317L are not adequate.

SILVER TUBES stocks stainless steel 904L tubes (UNS N08904) for use in applications that require moderate to high corrosion resistance.

Because of the combination of relatively high contents of chromium, nickel, molybdenum and copper, this grade has greatly improved resistance to strong reducing acids, particularly sulfuric acid. Stainless steel 904L tubes are also extremely resistant to chloride attack from both pitting/crevice corrosion and stress corrosion cracking. Stainless steel 904L tubes are non-magnetic in all conditions, possess amazing toughness and has good formability and weldability.

Stainless steel 904L tubes are often specifically used when sulfuric or phosphoric acids are involved because of its excellent resistance to corrosion from those acids. The paper industry, gas industry, pharmaceutical industry and chemical industries also use stainless steel 904L tubes for its resistance properties and good use up to 400-450 degrees C. Stainless steel 904L Tubes can be welded, machined, heat treated, annealed, hardened and cold worked for many purposes.
