Introduction of 904L stainless:
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 of 904L stainless:
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.
Quality Standard of 904L stainless:
ASTM A182 Standard Specification for Forged or Rolled Alloy-Steel Pipe Flanges, Forged Fittings, and Valves and Parts
EN 10088 part3 stainless steel

Corrosion Resistance of 904L stainless:
Where a level of resistance to pitting corrosion better than 316 is required 904L stainless steel may be suitable. With its high nickel content at 25% it offers improved resistance to chloride stress corrosion cracking compared to other austenitic grades such as 304.
