Stainless Steel 904L Hollow Bars are a high-alloy austenitic stainless steel, primarily made up of 20% chromium, 25% nickel, 4.5% molybdenum, along with trace amounts of copper and manganese. This distinctive blend grants remarkable resistance to strong oxidizing acids, chloride-induced corrosion, and pitting. On the mechanical side, 904L showcases a tensile strength ranging from 485 to 620 MPa and a yield strength between 215 and 275 MPa, all while maintaining excellent ductility and toughness. Its low carbon content helps reduce sensitization during welding, preserving its corrosion resistance. Additionally, this material boasts good thermal stability, making it suitable for high-temperature and highly corrosive industrial applications.

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 find extensive use in the chemical processing, petrochemical, and pharmaceutical industries due to their exceptional corrosion resistance in harsh environments. They are perfect for crafting heat exchangers, pressure vessels, valves, pumps, and piping systems that deal with acidic or chloride-rich fluids. Moreover, 904L hollow bars are utilized in marine applications, seawater treatment plants, and upscale architectural structures that demand both durability and aesthetic charm. Their resistance to stress corrosion cracking and impressive mechanical strength further enhance their appeal in various applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
