Weston Stainless, based in Midland, UK, is a trusted supplier of high-quality stainless steel products, catering to industries such as construction, automotive, and manufacturing. Among their offerings, Stainless Steel 202 Flanges are widely recognized for their strength, durability, and moderate corrosion resistance. Manufactured in Grade 202, these flanges are available in various shapes, including weld neck, slip-on, blind, and socket weld flanges, ensuring reliable pipeline connections. Made from austenitic stainless steel with a balanced composition of chromium, nickel, and manganese, 202 flanges provide excellent mechanical properties, making them suitable for industrial piping, fluid transport, and structural applications.
Stainless Steel 202 Flanges consist of Chromium (17-19%), Nickel (4-6%), Manganese (7.5-10%), Carbon (≤0.15%), and Silicon (≤1%), offering high strength and moderate corrosion resistance. Their mechanical properties are tensile strength of ≥515 MPa, yield strength of ≥275 MPa, and elongation of ≥40%, ensuring toughness in harsh applications. The physical properties are density of 7.8 g/cm³, thermal conductivity of 16.3 W/m·K, and a melting point of 1400-1455°C. These properties render 202 flanges appropriate for structural, piping, and industrial use that demands strength, toughness, and resistance to moderate environmental exposure.
