Semih Metals supplies 304 hollow bars in a variety of sizes and custom specifications, catering to the diverse needs of sectors like chemical processing, food production, construction, marine, and mechanical engineering.
The **Stainless Steel 304 Hollow Bar** is an austenitic stainless steel that contains about 18% chromium and 8% nickel, along with a low carbon content, which gives it remarkable corrosion resistance and strength. It typically features a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of 40% over 50 mm. This material is non-magnetic when annealed and offers excellent weldability and machinability. The hollow design helps reduce weight without sacrificing strength, making it ideal for structural and mechanical applications where durability and precision are key.

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 Bar is commonly utilized in situations that require corrosion resistance, clean surface finishes, and high strength-to-weight ratios. It’s perfect for crafting machine parts, pump shafts, food processing equipment, marine components, and chemical containers. Its hollow structure is especially advantageous for applications that need to minimize material weight while still delivering strong mechanical performance. Industries that frequently use 304 hollow bars include petrochemical, pharmaceutical, automotive, and more.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
