Understanding Stainless Steel 904L – Alloy Chemistry and Performance

The stainless steel 904L is a super austenitic stainless steel that is designed to resist the most corrosive as well as oxidation conditions. It is usually composed of 19-23% chromium, 23-28% nickel, 4-5% molybdenum and trace copper that give:

  • Very high resistant to pitting and crevice corrosion even in high chloride environments.
  • Stabilization of oxidizing acids such as the sulfuric and nitric acid.
  • Welding The material is welded excellently with smooth fusion joints that do not need any complex post-weld treatment.
  • Excellent mechanical strength and durability in dimensions.

In comparison to traditional 300 series stainless steels, SS 904L features high exposure to extreme chemicals and is therefore suitable in industrial pipelines that deal with acids, brine or seawater.
