An Introduction to Super-Duplex Stainless Steels - Corrotherm
www.corrotherm.co.ukSuper-Duplex falls under the Duplex stainless steel grouping. Duplex stainless steels are graded for their corrosion performance depending on their alloy content. Today, modern Duplex stainless steel can be divided into four groups: • Lean Duplex such as 2304, which contains no deliberate Mo addition; • 2205, the work-horse grade accounting for
