Hengyang Piping - Super Austenitic Stainless Steel Pipes

Hengyang Piping offers the UNS S31254 super austenitic stainless steel pipe, known for its outstanding resistance to corrosion, especially in high-temperature and saline environments. This type of steel, also recognized as 254SMO or WNR 1.4547, is designed to provide high strength and excellent weldability, meeting stringent industry standards such as ASTM A269, A312, and A213. These properties make it particularly suitable for demanding applications such as seawater handling systems, desalination plant equipment, chemical processing, and flue gas desulphurization units. The pipes are manufactured to ensure compliance with minimum and maximum specifications on elements such as nickel, chromium, and molybdenum, contributing to its durability and performance in extreme conditions. With sizes ranging from 6-630mm in diameter and wall thicknesses of 0.5-45mm, these cold-drawn or cold-rolled pipes come with surface finish options, including pickled, passivated, polished, and bright annealed.
