Duplex & Super Duplex Steel

Duplex & Super Duplex Steel

All Duplex Steel are offered with an NACE 3.1 Certification, Mill Test Certification and ISO 17025. Duplex Steel were originally created to combat corrosion problems caused by chloride-bearing cooling waters and other aggressive chemical process fluids. Called Duplex because of its mixed microstructure with about equal proportions of ferrite and austenite, duplex stainless steels are a family of grades, which range in corrosion performance depending on their alloy content.
