220S Duplex Stainless Steel - CRP

2205 Duplex Stainless Steel Description The 2205 (UNS S31803) alloy is probably the most recognized and widely used of the many Duplex Stainless steels. As the name Duplex implies, it has a dual phase microstructure of both austenite and ferrite. In other words, Duplex alloys have the strength of ferritic (400 series) while retaining the corrosion resistance of the austenitic (300 series) Corrosion The Duplex Stainless steels have general corrosion resistance comparable Resistance to 316 and even exceed it in many applications. In addition, their particular combination of higher chromium, molybdenum and nitrogen gives the duplexes more resistance to localized forms of corrosion such as pitting, crevice and stress corrosion cracking. Since 2205 lacks the copper addition of CD4 MCuN, it would not be expected to do as well as CD4 MCuN in sulfuric acid. Mechanical Like all Duplex Stainless steels, 2205 has approximately twice the yield Properties strength of 316 Stainless and it is also about 50% harder.
