Weston Stainless, based in Midland, UK, is a leading supplier of high-quality stainless steel products, serving industries such as construction, automotive, and manufacturing. Among its extensive range, Stainless Steel 202 Fasteners are highly regarded for their strength, durability, and moderate corrosion resistance. Manufactured in Grade 202, these fasteners are available in various shapes, including bolts, nuts, washers, screws, and studs, catering to diverse industrial fastening needs. Made from austenitic stainless steel with a balanced composition of chromium, nickel, and manganese, 202 fasteners provide excellent mechanical performance, making them ideal for structural, machinery, and general-purpose applications in demanding environments.
Stainless Steel 202 Fasteners consist of Chromium (17-19%), Nickel (4-6%), Manganese (7.5-10%), Carbon (≤0.15%), and Silicon (≤1%), providing excellent strength and moderate corrosion resistance. Their mechanical properties involve a tensile strength of ≥515 MPa, yield strength of ≥275 MPa, and elongation of ≥40%, providing strength and reliability in rigorous applications. The physical characteristics comprise a density of 7.8 g/cm³, thermal conductivity of 16.3 W/m·K, and melting point between 1400-1455°C. All these characteristics render 202 fasteners suitable for use in structural, automotive, and industrial applications where strength, toughness, and resistance to wear are needed.
