About 904L Stainless Steel Pipe
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.
904L stainless steel combines molybdenum and copper with iron for tremendously increased resistance to reducing acids like sulphuric acid. It stands up extremely well to chlorides in the environment for low pitting and crevice corrosion, as well as stress corrosion cracking.

Applications
904L stainless steel is widely used in the chemical, pharmaceutical, oil and gas industries. Typical applications include tanks, valves, heat exchangers, flanges and manifolds. The addition of copper to the composition of 904L stainless steel aids its suitability for components such as tanks and other products used in handling sulphuric and phosphoric acid.
