2.2205 duplex stainless steel is a mix of austenite and ferrite, giving the material improved strength over standard grades. Duplex stainless is a mixed microstructure of austenite and ferrite (50/50), which has improved strength over ferrite and austenitic steel grades with similar corrosion resistance qualities.

3.One of the main attractions of duplex stainless steel is cost – due to the materials increased yield strength, it is often possible to reduce the thickness of the material, making it much cheaper than a comparative austenitic stainless steel grade.

4.Also, Duplex steel has a lower alloy content reduces production costs. Certainly, cost and weight savings without loss of performance is an attractive proposition to purchasers.

5.Benefits of using UNS32205 Duplex Stainless Steel

Corrosion resistance much better than that of Type 316

Greater tensile and yield strength

Good ductility and toughness though not as good as austenitic grades

Good stress corrosion cracking resistance (SSC)

Opportunity for purchases to reduce their material costs without compromising on quality

6.About 2205

2205 is the most common duplex alloy, which contains 22% chromium and 5% nickel. Please refer to the chemical composition and mechanic properties tables below. For information on “Super Duplex,” which provides higher corrosion resistance, please click on the links to Super Duplex grades at the top of this page.
