Khush Sheets and Plates is a well-known SMO 254 Sheet and Plates manufacturer and supplier in Kolkata, India, offering top-quality stainless steel solutions for highly corrosive and demanding conditions. SMO 254 is a high-alloy austenitic stainless steel with superior corrosion resistance, particularly in seawater and aggressive chemical environments. At Khush Sheets and Plates, we provide SMO 254 Sheets and Plates that are specifically designed according to international standards, utilized in industries like offshore, chemical processing, and marine. Our focus on quality, timely delivery, and customer satisfaction makes us a reliable industry partner.
SMO 254 Sheets and Plates consist of chromium (19.5–20.5%), nickel (17.5–18.5%), molybdenum (6–6.5%), nitrogen (0.18–0.22%), and copper (0.5–1%), with iron. The special combination offers good resistance to pitting, crevice corrosion, and stress corrosion cracking. SMO 254 contains a tensile strength of about 650 MPa and a yield strength of about 300 MPa, with good ductility and impact toughness. It is not magnetic and can be easily welded and fabricated. Such mechanical and chemical properties make it the best for severe and chloride-contaminated environments.
