SS 904L / UNS N08904 Tubes
Premium 904L Stainless Steel Tubes for High-Performance Industrial Applications
Our 904L Stainless Steel Tubes are manufactured to deliver exceptional performance in demanding industrial environments where superior corrosion resistance, durability, and reliability are essential. Available in Seamless and Welded forms, our SS 904L Tubes are widely used in chemical processing, heat exchangers, condensers, instrumentation systems, hydraulic equipment, marine applications, and other critical industries.
Manufactured from UNS N08904, our tubes provide excellent resistance to pitting, crevice corrosion, and reducing acids, making them an ideal choice for applications involving aggressive chemicals and chloride-rich environments. We also offer Custom 904L Tubes in various sizes, wall thicknesses, and lengths to meet project-specific requirements.
What Makes SS 904L Tubes Suitable?
SS 904L / UNS N08904 Tubes offer excellent resistance to pitting, crevice corrosion, chloride attack, and aggressive acids. Their high chromium, nickel, molybdenum, and copper content makes them suitable for demanding chemical processing, pharmaceutical, marine, and industrial applications.
These tubes provide reliable performance where conventional stainless steel may require greater corrosion resistance, durability, and long-term service.
Our 904L Stainless Steel Tube range is engineered for applications requiring outstanding corrosion resistance, excellent mechanical properties, and long service life. Manufactured using premium-quality raw materials, our 904L Seamless Tubes and 904L Welded Tubes are suitable for both standard industrial installations and specialized engineering projects.
SS 904L Tube is a fully austenitic, low-carbon stainless steel containing enhanced levels of nickel, molybdenum, and copper. This unique composition provides excellent resistance to pitting, crevice corrosion, and reducing acids such as sulphuric and phosphoric acid, making it a preferred material for highly corrosive service conditions.
Our product range includes ASTM A269 TP904L Tubes, ASTM A213 TP904L Tubes, precision tubes, heat exchanger tubes, condenser tubes, instrumentation tubes, and hydraulic tubes manufactured to meet international quality standards.
Our 904L Stainless Steel Tubes are designed to deliver dependable performance across a wide range of industrial applications.
