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. With a focus on durability and precision, Weston Stainless provides corrosion-resistant solutions that meet international standards. Among its offerings, Stainless Steel 317 Fasteners are known for their superior strength and resistance to acidic environments. Made from molybdenum-bearing austenitic stainless steel, these fasteners provide excellent corrosion resistance. Available in various shapes, including bolts, nuts, screws, and washers, they ensure strong and reliable fastening solutions for demanding industrial applications.
Stainless Steel 317 Fasteners are composed of iron, chromium (18-20%), nickel (11-15%), molybdenum (3-4%), and low carbon content, enhancing corrosion resistance and strength. These fasteners exhibit excellent mechanical properties, with a tensile strength of approximately 620 MPa, yield strength of 275 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 exceptional resistance to pitting, crevice corrosion, and oxidation, these fasteners are ideal for harsh environments, ensuring long-lasting performance in high-pressure and high-temperature applications.
