ZERON® 100

ZERON® 100 (F55 Duplex / 25Cr Duplex) is a super duplex stainless steel for use in aggressive environments.

ZERON® 100 complies with UNS S32760, however, Rolled Alloys tightly controls the chemistry and production of ZERON® 100 in strict accordance with the requirements of our in-house ‘MDS’ specifications which are tighter than standard ASTM specifications. This ensures a consistent quality product is produced with optimal corrosion resistance and charpy impact toughness.

ZERON® 100 was developed as a seawater resistant material for pump applications in the North Sea as a cast material. Its excellent performance, led to demand for the alloy in a wider range of product forms and the development of wrought product forms. The corrosion resistance and strength properties of ZERON® 100 have led to its widespread adoption in a range of industries. Oil and gas applications include process, seawater, firewater and subsea pipework systems, with associated risers, manifolds, pressure vessels, valves and heat exchangers. Applications of ZERON® 100 (UNS S32760) in other industries include pollution control equipment such as flue gas desulfurization equipment (FGD), pulp and paper, power generation, chemical, pharmaceutical, desalination, mining, metallurgical and marine industries.
