What is Duplex 2205 Stainless Steel?

Duplex 2205 is a two-phase ferritic/austenitic – structures are approximately 50/50 austenite and ferrite and physical properties are a combination of the ferritic and the austenitic grades. It is the most widely used nitrogen enhanced duplex stainless steel grade and is characterized by high yield strength, double that of the standard austenitic stainless steel grades.It was developed to combat common corrosion problems encountered with the 300 series stainless steels. It demonstrates good fatigue strength, as well as outstanding resistance to stress-corrosion cracking, crevice, pitting, erosion and general corrosion in severe environments. Duplex Steel 2205 is not generally suitable for use at temperatures above 300°C as it suffers from precipitation of brittle micro-constituents, nor below -50°C because of its ductile-to-brittle-transition. It finds applications due to both excellent corrosion resistance and high strength. “Duplex” describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430.

Duplex family consists of:

  • Lean Duplex SS – lower nickel and no molybdenum – 2101, 2102, 2202, 2304
  • Duplex SS – higher nickel and molybdenum – 2205, 2003, 2404
  • Super Duplex – 25Chromium and higher nickel and molybdenum “plus” – 2507, 255 and Z100
  • Hyper Duplex – More Cr, Ni, Mo and N – 2707
