Weston Stainless, a Midland, UK-based company, is a reliable source of top-quality stainless steel products, serving diverse industries with precision-fabricated materials. Of its products, SMO 254 Coils are a top recommendation for challenging uses. SMO 254 Coils are made from SMO 254, a high-alloy austenitic stainless steel that is renowned for its excellent corrosion resistance, particularly in chloride-bearing environments. In the form of strips and rolls, these coils provide superior strength, weldability, and durability. With a high molybdenum content, SMO 254 Coils find extensive application in marine, chemical, and desalination applications, providing long-lasting performance.
SMO 254 Coils consist of around 20% of chromium, 18% nickel, 6% molybdenum, 1% nitrogen, and low carbon content, which increases corrosion resistance. Mechanically, they provide tensile strength of around 650 MPa, yield strength of 300 MPa, and elongation of 35%, which results in superior durability and formability. Physical properties consist of a density of 8 g/cm³, thermal conductivity of 14.5 W/m·K, and a melting range of 1320-1390°C. These characteristics make SMO 254 Coils suitable for severe environments, with outstanding resistance to pitting, stress corrosion cracking, and high-temperature oxidation.
