SMO 254 Tube Fittings

Home > Stainless Steel > SMO 254 Tube Fittings

SMO 254 Tube Fittings are crafted from SMO 254 alloy (UNS S31254), a super austenitic stainless steel that contains about 20% chromium, 18% nickel, 6% molybdenum, and 0.2% nitrogen. This unique blend offers outstanding corrosion resistance, particularly against chlorides and acidic environments. The fittings boast impressive tensile strengths ranging from 75,000 to 85,000 psi, along with excellent toughness and resistance to stress corrosion cracking. With precision machining and rigorous quality control, we ensure tight sealing surfaces and durable mechanical performance, making them ideal for high-pressure and high-temperature industrial applications.
