904L stainless steel is a superaustenitic stainless steel grade, Alloy 904L (UNS N08904) contains high levels of chromium and nickel with additions of molybdenum and copper to provide superior corrosion resistance.
The combination of high chromium and nickel content, coupled with additions of molybdenum and copper, assures good to excellent corrosion resistance, and moderate to high corrosion resistance in a wide range of process environments, containing dilute sulfuric acid. It also offers good resistance to other inorganic acids such as hot phosphoric acid as well as most organic acids.

Processing / Welding
Standard welding processes for this steel grade are:
- TIG-Welding
- MAG-Welding Solid Wire
- Arc Welding (E)
- Laser Bean Welding
- Submerged Arc Welding (SAW)
Application of 904L Stainless Steel
Chemical plant, oil refinery, petrochemical plants, bleaching tanks for the paper industry, combustion gas desulfurisation plants, application in sea water, sulphuric and phosphoric acid. Due to the low C-content, the resistance to intergranular corrosion is also guaranteed in the welded condition.
