Weston Stainless, based in Midland, UK, is a trusted supplier of high-quality stainless steel products, serving industries such as oil & gas, petrochemicals, marine, and construction. Committed to precision and durability, Weston Stainless provides corrosion-resistant solutions that meet global standards. Among its offerings, Stainless Steel 321 Bars are widely used for their excellent strength and high-temperature resistance. Made from titanium-stabilized austenitic stainless steel, these bars offer superior corrosion resistance and durability. Available in various shapes, including round, square, and hex bars, they provide reliable performance in demanding industrial applications, especially in heat-intensive environments.
Stainless Steel 321 Bars are composed of iron, chromium (17-19%), nickel (9-12%), titanium (at least 5x the carbon content), and low carbon, enhancing corrosion and oxidation resistance. These bars exhibit excellent mechanical properties, with a tensile strength of approximately 515 MPa, yield strength of 205 MPa, and elongation of 40%. Their physical properties include a density of 7.9 g/cm³ and a melting point of 1398-1446°C. With superior resistance to intergranular corrosion, high temperatures, and oxidation, these bars ensure durability and reliability, making them ideal for heat-intensive and high-pressure industrial applications.
