General Proprieties

The 904L steel (UNS N08904) is a superaustenitic stainless steel that is designed for moderate to high corrosion resistance in a wide range of process environments. The combination of high chromium and nickel content, coupled with additions of molybdenum and copper, assure good to excellent corrosion resistance. The 904L steel is commonly used in reactors, parts of distilling equipment and pipes for equipment handling highly aggressive chemicals: sulphuric, phosphoric, nitric, hidrocloric, acetic acids. Highly resistant in contact with chlorine ions. The 904L steel is available at CHUN & VOLLERIN in the following formats: Bars, Plates, Pipes, Stripes.
