Stainless Steel 904L Pipe Fittings consist of high chromium content (19–23%), nickel content (23–28%), molybdenum content (4–5%), and minor content of copper. Its exceptional resistance to reducing acids such as sulfuric acid, stress corrosion cracking, and pitting in chloride-containing environments is offered by this one-of-a-kind composition. Its tensile strength of approximately 490 MPa along with yield strength of 220 MPa makes 904L a combination of strength and good ductility and weldability. It also has good performance at high temperatures and long-time corrosion resistance, which makes it well suited for harsh industrial applications where regular stainless steels can fail.

Stainless Steel 904L Pipe Fittings are employed in highly corrosive atmospheres where normal grades such as 304 or 316 are insufficient. In chemical and petrochemical plants, they are utilized in equipment dealing with sulfuric, phosphoric, and acetic acids. For seawater cooling systems and offshore platforms, 904L fittings are resistant to corrosion by seawater. The food processing and pharmaceutical industry use these fittings for their non-contaminating, corrosion-proof nature. They are also used in gas scrubbers, pulp and paper mills, and heat exchangers. Their weldability, chemical resistance, and durability make them best suited for long-term, high-integrity piping systems.
