Product Details

Super Ferritic Stainless Steel UNS #S44660 pipe

S44660 Description

The ferritic structure of UNS #S44660 Stainless steel provides a high strength/low work hardening material with good ductility.

This alloy is specifically designed for applications where chloride induced pitting, crevice, and stress corrosion cracking may be encountered.

UNS #S44660 stainless steel is used in electric power plant condensers and BOP exchangers, various heat exchangers in chemical, petrochemical, and refining applications, desalinationheat exchangers and flue gas handling systems .

The American Gas Association has approved UNS #S44660 for flue gas condensate applications. UNS #S44660 stainless steel has better resistance to general corrosion over a broader range of conditions than the austenitic stainless steels.
