Super Duplex Steel Sheet

Neptune Alloys is a leading Super Duplex Steel Sheet manufacturer delivering corrosion resistant sheets engineered for aggressive and high pressure environments. These sheets are made from high performance alloys like UNS S32750 and S32760 offering superior mechanical strength, pitting resistance, and thermal stability. Commonly used in marine offshore oil rigs, desalination plants, and heat exchangers, they provide dual phase austenitic ferritic structure, ensuring both strength and corrosion protection in chloride laden systems. 

We provide sheets in compliance with ASTM A240 and equivalent international standards for critical B2B applications. Each sheet is rigorously tested for tensile strength, impact resistance, and intergranular corrosion. Clients can choose from custom dimensions, sheet widths, thicknesses, and surface finishes, including hot-rolled, cold-rolled, and pickled. Backed by strong production capabilities and streamlined logistics, we ensure timely supply to EPCs, process industries, and offshore engineering sectors in India and abroad.
