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.
