904L Stainless Steel Pipe/Tube
Type 904L (UNS N08904) is a non-stabilized, high-alloy super austenitic stainless steel. With the critical addition of 1.5% Copper, 904L provides exceptional resistance to strong reducing acids, particularly sulphuric acid in various concentrations.
Where 316L fails in highly corrosive environments like phosphoric acid production or seawater handling, our 904L tubes deliver the structural integrity and long-term reliability your critical projects demand.
The performance of 904L depends strictly on its alloy balance.
Premium Alloy Control: We ensure Nickel and Molybdenum levels are kept well above the minimum requirements, providing a superior safety margin for your engineering applications.
Non-Destructive Testing (NDT): Standard procedures include Hydrostatic and Ultrasonic testing to ensure zero-defect delivery for high-pressure environments.
Full Traceability: Every order is dispatched with a verified EN 10204 3.1 Mill Test Certificate, linking every pipe to its original heat number.
Ready-to-Ship Inventory: Leveraging our strategic position in Wuxi, China, we offer rapid turnaround times for 904L pipes, helping you avoid project delays caused by material shortages.
Custom Processing: We offer precision cutting, beveling, and customized packaging to meet your specific on-site installation requirements.
Export Logistics Expertise: We specialize in serving international clients across Southeast Asia, the Middle East, and beyond, ensuring all documentation (Certificate of Origin, Form E, etc.) is perfectly aligned for duty-free or smooth customs entry.
Reliable Packaging: We use reinforced seaworthy wooden cases to protect high-value 904L products from surface damage and moisture during long-distance transit.
