Weston Stainless, based in Midland, UK, is a leading supplier of premium stainless steel products, catering to industries such as oil & gas, petrochemicals, marine, and construction. Committed to quality and precision, Weston Stainless provides durable and corrosion-resistant solutions that meet global standards. Among its offerings, Stainless Steel 317L Bars are highly valued for their superior strength and resistance to acidic environments. Made from low-carbon, molybdenum-bearing austenitic stainless steel, these bars provide excellent corrosion resistance and durability. Available in various shapes, including round, square, and hex bars, they ensure reliable performance in demanding industrial applications.
Stainless Steel 317L Bars are composed of iron, chromium (18-20%), nickel (11-15%), molybdenum (3-4%), and low carbon content, enhancing corrosion resistance and weldability. These bars have excellent mechanical properties, including a tensile strength of approximately 620 MPa, yield strength of 260 MPa, and elongation of 35%. Their physical properties include a density of 7.9 g/cm³ and a melting point of 1370-1400°C. With superior resistance to pitting, crevice corrosion, and oxidation, these bars ensure durability and reliability, making them ideal for high-temperature and high-pressure applications in harsh industrial environments.
