Stainless Steel 304 Bars and Rods are well-known for their outstanding resistance to corrosion, impressive durability, and versatility across a range of industrial applications. As the most popular austenitic stainless steel grade, SS 304 strikes a perfect balance between strength, formability, and long-lasting performance. These bars and rods come in various finishes and sizes, making them ideal for fabrication, machining, and structural purposes. Their ability to resist oxidation, moisture, and chemical exposure ensures reliable performance in tough environments, including construction, food processing, petrochemical, and marine industries.
Made up of roughly 18% chromium and 8% nickel, Stainless Steel 304 Bars and Rods offer remarkable corrosion resistance and stability. They boast mechanical properties like a tensile strength of about 515–620 MPa and a yield strength of around 205 MPa, providing dependable strength for structural and load-bearing tasks. With excellent ductility, weldability, and formability, SS 304 retains its toughness even in low temperatures. Its non-magnetic nature when annealed and its ability to resist atmospheric and chemical corrosion make it a go-to choice in various manufacturing processes.
