Weston Stainless, which has its base in Midland, UK, is a reputable exporter of prime stainless steel products such as Stainless Steel 422 Fasteners. The fasteners are produced with the use of grade 422 stainless steel, a heat– and corrosion-resistant martensitic alloy with high strength. These fasteners come in different shapes like bolts, nuts, washers, screws, and studs and are made to withstand the stringent demands of industries such as aerospace, power generation, and marine engineering. With better mechanical properties and strength, Stainless Steel 422 Fasteners are suitable for applications where high-temperature strength and resistance to oxidation are needed.
Stainless Steel 422 Fasteners have iron as their major constituent with 12% chromium to impart corrosion resistance, 0.20-0.25% carbon for hardening, and other constituents such as molybdenum, tungsten, and vanadium for further improving the performance at elevated temperatures. They possess tensile strength of 965 MPa, yield strength of 827 MPa, and elongation of 15% due to which they can find application in adverse conditions. With a density of 7.8 g/cm³, these fasteners offer superior thermal conductivity and oxidation resistance to 1200°F (650°C), providing stability in high-stress applications.
