Known for their impressive corrosion resistance, durability, and versatility, these hollow bars are perfect for a variety of industrial and commercial uses. Stainless Steel 304 is celebrated for its remarkable strength and resistance to oxidation in both atmospheric and chemical settings. At Sadiki Metals, every hollow bar is crafted to meet international quality standards, ensuring that industries get reliable, precise, and long-lasting stainless steel solutions for their high-performance needs.
Stainless Steel 304 Hollow Bars are made from an austenitic stainless steel alloy that contains 18–20% chromium, 8–10.5% nickel, and a low carbon content (≤0.08%). This unique blend offers outstanding corrosion resistance, solid mechanical strength, and excellent formability. The material boasts a tensile strength of about 515–700 MPa, a yield strength of around 205–275 MPa, and an elongation rate exceeding 40%. Additionally, 304 hollow bars provide good toughness, dimensional stability, and resistance to oxidation, making them ideal for structural, precision, and high-durability applications.

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.
Stainless Steel 304 Hollow Bars find extensive use in industries that demand corrosion resistance, strength, and reliability. They are commonly utilized in chemical processing equipment, heat exchangers, pipelines, valves, fasteners, food and beverage machinery, and marine components. Furthermore, they serve in structural and decorative applications where both aesthetic appeal and durability are crucial. Sectors such as chemical, pharmaceutical, food processing, and construction depend on 304 hollow bars to provide dependable, long-lasting components that can endure challenging operational conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
