Smo 254 & Alloy 20 Pipes

img

SMO 254 & Alloy 20 Pipes are high-performance alloy pipes designed for demanding corrosive environments, particularly in chemical processing, petrochemical, offshore, and desalination applications. SMO 254 (UNS S31254) is a super austenitic stainless steel with very high molybdenum and nitrogen content, providing outstanding resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Alloy 20 (UNS N08020) is a nickel-iron-chromium alloy developed specifically for sulfuric acid service, offering excellent resistance to general corrosion, intergranular attack, and acid-induced stress corrosion.

These pipes are manufactured in seamless and welded forms as per international standards such as ASTM A312, ASTM A269, and ASTM B729, ensuring consistent mechanical strength and dimensional accuracy. SMO 254 & Alloy 20 pipes are widely used in heat exchangers, reactors, acid handling systems, power plants, and marine equipment due to their high strength, excellent weldability, and long service life under high temperature and aggressive chemical conditions.
