Stainless Steel 304 Hollow Bar is an austenitic alloy that contains about 18–20% chromium and 8–10.5% nickel. This unique blend gives the material outstanding resistance to oxidation and corrosion across a wide range of environments. It boasts a tensile strength of around 515 MPa, a yield strength of approximately 205 MPa, and an elongation of about 40%. Thanks to its low carbon content and well-balanced alloying, it offers excellent weldability, formability, and strength. SS 304 hollow bars maintain their structural integrity in both normal and elevated temperatures, making them perfect for machining and structural applications where internal bore access is essential.

SS 304 Hollow Bar offers excellent corrosion resistance, superior to carbon steel but lower than SS 316. It's effective in mildly corrosive environments, such as atmospheric, food processing, and water systems.
SS 304 Hollow Bars are produced through extrusion, drawing, and machining. These processes refine the material's structure, enhancing strength, ductility, and surface finish, ensuring optimal mechanical properties for various applications.
These Stainless Steel 304 Hollow Bars are popular across various industries due to their strength, corrosion resistance, and hollow design, which helps reduce weight without sacrificing performance. In the automotive and aerospace fields, they are commonly used for shafts, spacers, and load-bearing components. In the chemical and food processing sectors, they serve in fluid transport systems, condensers, and machinery that requires high hygiene standards. Construction and marine applications also utilize 304 hollow bars for support structures and corrosion-resistant frameworks. Plus, their machinability and cost-effectiveness make them a go-to choice for precision engineering, mechanical parts, and general fabrication that requires internal access.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
