Aditya Stainless stands out as a trusted manufacturer and supplier of SMO 254 Pipe Fittings right in Kolkata, India. We specialize in delivering high-performance solutions tailored for tough, corrosive environments. SMO 254 (UNS S31254) is a super austenitic stainless steel known for its exceptional resistance to chloride-induced corrosion, pitting, and crevice attack, making it perfect for applications in chemical processing, marine settings, offshore operations, and desalination. Our product lineup features elbows, tees, reducers, crosses, and caps, all crafted to meet ASME/ANSI, DIN, and various international standards. With outstanding weldability, strength, and durability, SMO 254 pipe fittings guarantee leak-proof, long-lasting connections, even in high-pressure and high-temperature systems.
SMO 254 Pipe Fittings are made up of 20% chromium, 18% nickel, 6% molybdenum, 0.2% nitrogen, and low carbon content, which gives them remarkable corrosion resistance, particularly in chloride-rich and acidic settings. They boast impressive mechanical strength, with a tensile strength of at least 650 MPa, yield strength of at least 300 MPa, and an elongation of at least 35%. These fittings are highly resistant to stress corrosion cracking, making them suitable for extreme conditions. Their austenitic structure ensures they remain tough, even in sub-zero temperatures. Plus, the smooth internal finish and excellent weldability make SMO 254 pipe fittings a top choice for demanding industrial applications.
