Description

904L is a high-alloy austenitic stainless steel with low carbon content. The grade is intended for use under severe corrosive conditions. It was originally developed to resist corrosion in dilute sulfuric acid and has been proven effective in this application over many years. Structurally, 904L is fully austenitic and is less sensitive to precipitation ferrite and sigma phases than conventional austenitic grades with high molybdenum content. 904L has a good resistance to general corrosion, particularly in sulfuric and phosphoric conditions.

Typical Applications

• Production and transport of sulfuric acid
• Metal picking in sulfuric acid
• Production and concentration of phosphoric acid
• Use in seawater, brackish water, condensers, heat exchangers, and general pipe work
• Paper and allied industries
• Gas washing
