Premium 904L stainless steel tube with excellent acid corrosion resistance. Custom sizes and shapes available from China’s trusted stainless steel tube manufacturer. Seamless or welded options with global certifications.
As a leading stainless steel tube manufacturer in China, we provide 904L stainless steel tubes specifically designed for extreme corrosion resistance in highly acidic and chloride-rich environments. 904L is a non-stabilized austenitic stainless steel with added copper to improve resistance to strong reducing acids like sulfuric acid. It offers excellent weldability, formability, and maintains a non-magnetic structure in all conditions.
Our factory supports full customization of dimensions, surface finish, and technical specifications, enabling us to serve industries such as chemical processing, marine engineering, gas scrubbing systems, and pulp & paper. All products conform to ASTM, EN, DIN, and JIS standards and are supported with EN10204 3.1/3.2 certificates.
