UNS S31254 - EN 1.4547

UNS S31254 - EN 1.4547 is a stainless steel grade that provides excellent corrosion resistance and high strength. It is composed of 19.5-20.5% Cr, 17.0-19.0% Ni, 6.0-7.0% Mo, and traces of other elements for improved properties. Its excellent resistance to chloride pitting and crevice corrosion make it a great choice for components that must withstand high levels of chloride exposure.

Description

Essential details

EN 1.4547 is described as a 6% Mo super austenitic stainless steel. The steel combines moderate mechanical strength (typically over 300 MPa yield strength) and high ductility with excellent corrosion resistance in seawater and a variety of industrial environments.

Typically the alloy has a PREn(Pitting Resistance Equivalent) of 42-44 which ensures that the resistance to pitting corrosion is high. In addition, the steel provides good resistance to crevice corrosion.
