Good news! We’ve developed a super-austenitic stainless steel alloy called Sanicro® 35. It is easy to work with and bridges many material property gaps between stainless steel and costly nickel alloys. The alloy won the materials design category in the Materials Performance Corrosion Innovation of the Year Awards in 2021 hosted by AMPP.
Sanicro is the trademark name for our family of high-alloy, multi-purpose stainless steels. As a member, Sanicro® 35 (UNS N08935) is a structurally stable, PRE 52 super-austenitic alloy that offers extreme localized corrosion resistance and outperforms conventional 6Mo grades, with only moderate nickel content.
Designed for service in aggressive corrosive environments, the material bridges gaps between standard duplex or austenitic grades and nickel alloys. It offers the desirable corrosion resistance of high nickel grades as demonstrated by its extreme critical pitting and crevice temperatures combined with excellent mechanical properties.
