What is Zeron100?

Zeron100 was originally developed by Dr. Cecil Roscoe while working at Mather+Platt in Manchester, England. Mather+Platt successfully marketed Zeron100 primarily in the manufacturing of their advanced centrifugal pumps for the oil industry.

 The use of super duplex stainless steels for such applications was obvious, given the potentially aggressive solutions to be handled, requiring significant corrosion resistance, strength and wear resistance. Hence, the team at Mather+Platt sought to optimize ease of casting and long-term performance of their pump bodies for more demanding applications. The wrought form of Zeron100 was licensed by Mather+Platt, to British Steel.

 Subsequently, when Weir Pumps purchased the pump division of Mather+Platt, they took over the material, but they were not the original developers of Zeron100.

 The Zeron100 trademark is now held by Rolled Alloys Inc.

 This particular grade is more widely referred to as Alloy S32760 (UNS S32760, 1.4501, F55). It utilizes the 25% chromium content of other super duplex stainless steels, but also includes a deliberate addition of tungsten, claimed to selectively improve corrosion resistance. Zeron100 has a copper addition which provides good resistance to sulfuric acid. For this reason, it is used in acid leach mining applications, steel pickling and other industries where sulfuric acid is encountered. Zeron100 has a 50–50 austenitic–ferritic structure.

 Zeon stocks Alloy S32760 in Solid Bars, Plates & Pipes.

 Zeon also converts S32760 into Finished Products like Fasteners, Flanges & Pipe Fittings for direct applications.
