Stainless Steel Square Bar
Stainless Steel Square Bar is a high-strength, corrosion-resistant alloy bar with a square cross-section, crafted from grades such as 304, 316, 303, and 430. Composed primarily of iron, chromium (10.5–30%), nickel (in austenitic grades), and other elements, it offers exceptional durability, heat resistance, and anti-corrosive properties, making it ideal for harsh environments. These bars are available in widths ranging from 5mm to 100mm and standard lengths of 3m or 6m, with surface finishes including hot-rolled (rough), cold-drawn (smooth), and polished (mirror-like). Applications span construction frameworks, marine hardware, automotive components, architectural trim, and food/medical equipment. Compliant with ASTM A276, A479, and EN standards, they are supplied solution-annealed for optimal performance and packaged in corrosion-protected bundles or crates.
