Stainless Steel 904L Hollow Bar is a high-alloy austenitic stainless steel that features elevated levels of chromium, nickel, molybdenum, and copper, along with very low carbon content. This unique composition grants it remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in acidic and chloride-rich settings. On the mechanical side, 904L Hollow Bars deliver good tensile strength, high toughness, and excellent ductility. They maintain their strength even at elevated temperatures and perform admirably under pressure, all while offering good weldability and formability without sacrificing corrosion resistance.

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.
These Stainless Steel 904L Hollow Bars find extensive use in industries that demand superior corrosion resistance and structural reliability. They’re commonly utilized in chemical processing equipment, heat exchangers, pressure vessels, and piping systems that handle aggressive acids. The material is also favored in the oil and gas sector, offshore platforms, pollution control systems, and desalination plants due to its resilience in harsh marine conditions. Furthermore, 904L Hollow Bars are essential in the pharmaceutical, food processing, and power generation industries, where hygiene, strength, and long-term performance are of utmost importance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
