Aditya Stainless stands out as a top manufacturer and supplier of Stainless Steel SMO 254 Bars in Kolkata, India. These premium-grade bars are specifically crafted to withstand extreme corrosion and high-strength applications. SMO 254 (UNS S31254) is a super austenitic stainless steel designed for chloride-rich environments, providing excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. Industries such as marine, offshore, chemical processing, pulp & paper, and desalination plants rely on these bars. Available in a variety of sizes, shapes, and finishes, SMO 254 bars are perfect for structural components, shafts, and high-performance fittings.
SMO 254 Bars are made up of about 20% chromium, 18% nickel, and 6% molybdenum, along with nitrogen and copper, which gives them outstanding chloride corrosion resistance and mechanical strength. These bars boast a tensile strength of at least 650 MPa, a yield strength of at least 300 MPa, and an elongation of around 35%, all while maintaining excellent impact toughness even in low temperatures. With a Pitting Resistance Equivalent Number (PREN) greater than 42, SMO 254 is well-suited for aggressive environments. The alloy also offers good weldability, formability, and fabrication characteristics, making it a dependable choice for both structural and pressure-based applications.
