Louis Metals offers high-quality Stainless Steel 904L Hollow Bars produced in Houston, USA, for applications requiring superior corrosion resistance and mechanical strength. 904L is a low-carbon high-alloy austenitic stainless steel that shows exceptional resistance to severe reducing acids and chloride-induced corrosion. Our hollow bars are perfect for machining and producing bushings, rings, couplings, and custom cylindrical parts. Manufactured to ASTM A511 and A312 specifications, Louis Metals provides seamless and welded hollow bars in different sizes and thicknesses with high precision, smooth bore inner diameters, and uniform wall thickness for demanding industrial and engineering purposes.
904L contains 23–28% nickel, 19–23% chromium, 4–5% molybdenum, 1–2% copper, and trace carbon. It possesses tensile strength of approximately 490–710 MPa and a yield strength of ~220 MPa. The alloy is resistant to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich environments and concentrated sulfuric acid. With very good weldability and formability, 904L hollow bars are also non-magnetic and possess strength at high temperatures. Louis Metals guarantees high dimensional accuracy and clean inner surfaces for machining and fabrication 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.
904L Stainless Steel Hollow Bars find applications in marine hardware, pump cases, instrumentation tubing, and chemical processing equipment. They are suited for processes involving sulfuric, hydrochloric, or phosphoric acids because of their higher corrosion resistance. For applications in offshore platforms, 904L hollow bars are utilized in riser systems, manifolds, and pipeline fittings. Their machinability and internal dimensions to size capabilities qualify them for making bushings, roller sleeves, and high-pressure fittings. Louis Metals supplies custom-cut hollow bars for the pharmaceutical, desalination, pulp & paper, and gas processing markets, offering consistent performance in hostile and corrosive environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
