Weston Stainless, which is located in Midland, UK, is a reliable provider of high-quality stainless steel items, such as Stainless Steel 348 Bolts. The bolts are produced with grade 348 stainless steel, which is stabilized austenitic steel that possesses superior corrosion resistance, oxidation resistance, and strength at elevated temperatures. Engineered for critical stress conditions, these bolts are produced in many shapes, including hex bolts, U-bolts, carriage bolts, and anchor bolts, to industry specifications such as ASTM A193 and ASTM A320. With high resistance to intergranular corrosion and thermal stability, SS 348 Bolts find extensive use in critical industrial and structural applications.
Stainless Steel 348 Bolts have 17-20% chromium, 9-13% nickel, columbium (niobium), and low carbon for increased creep resistance and thermal stability. They possess tensile strength of 515 MPa, yield strength of 205 MPa, and elongation of 40%, which provides reliability under high pressure and temperature applications. Having a density of 7.9 g/cm³ and a melting point of about 1400°C, these bolts offer superior performance in oxidizing and high-heat applications.
