SS 904L stainless steel consists of approximately 24-26% chromium, 19-23% nickel, 4-5% molybdenum, 1-2% copper, and small amounts of manganese, silicon, and carbon. The copper enhances corrosion resistance, particularly in acidic environments, while maintaining high strength.
The typical diameter range for SS 904L hollow bars varies from 10 mm to 300 mm, although custom sizes can be manufactured. These bars are available in various wall thicknesses, depending on specific application requirements and industry standards.
Stainless Steel 904L Hollow Bars are a go-to choice in industries that demand top-notch corrosion resistance and durability. You’ll find them in chemical processing plants, marine settings, and oil and gas refineries. These bars are also utilized in heat exchangers, pulp and paper machinery, condenser tubes, and pollution control systems. Plus, they’re well-suited for architectural structures, pharmaceutical equipment, and desalination plants. Thanks to their outstanding strength, weldability, and resistance to harsh chemicals, they’re an ideal fit for both structural and process engineering projects.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
