Tiub keluli tahan karat 904L premium dengan ketahanan kakisan asid yang cemerlang. Saiz dan bentuk tersuai tersedia daripada pengeluar tiub keluli tahan karat terkemuka di China. Pilihan tanpa jahitan atau disalut dengan pensijilan global.
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.
