Alloy Metals and Tubes International stocks alloy 904L tubing (UNS N08904) for use in applications that require moderate to high corrosion resistance. Alloy 904L is a low carbon high alloy austenitic stainless steel, originally developed to resist corrosion in dilute sulfuric acid. Because of the combination of chromium, nickel, molybdenum and copper, this grade has greatly improved resistance to strong reducing acids, particularly sulfuric acid. Alloy 904L tubing is also extremely resistant to chloride attack from both pitting/crevice corrosion and stress corrosion cracking. Alloy 904L is non-magnetic in all conditions, possesses amazing toughness, and has good formability and weldability.

Because of these properties, one can find alloy 904L tube in many applications. These range from utility scrubber assemblies to acid and fertilizer production equipment, pulp and paper processing, seawater cooling facilities. Used in processes containing sulfuric or phosphoric acids, 904L displays its excellent resistance to corrosion from those acids. The paper, gas, pharmaceutical and chemical industries also use 904L for its resistance and use to 400-450 degrees C. Alloy 904L tubing can be welded, machined, heat treated, annealed, hardened and cold worked for many purposes.

Alloy Metals and Tubes International stocks Alloy 904L tubing to meet the diverse needs of customers in varied markets and applications, and seeks to be your preferred quality supplier of Alloy 904L tube. Contact us, or send us a request for a quote today.
