2205 Duplex Overview

 

Duplex 2205 is a nitrogen enhanced duplex stainless steel that was developed to combat

common corrosion problems encountered with the 300 series stainless steels. “Duplex”

describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor

purely ferritic, like 430 stainless. The structure of 2205 duplex stainless steel consists of

austenite pools surrounded by a continuous ferrite phase. In the annealed condition, 2205

contains approximately 40-50% ferrite. Often referred to as the work horse grade, 2205 is

the most widely used grade in the duplex family of stainless steels.

The advantage of a duplex structure is that it combines the favorable qualities of a ferritic

alloy (stress corrosion cracking resistance and high strength) with those of an austenitic alloy

(ease of fabrication and corrosion resistance).

Usage of 2205 Duplex stainless steel should be limited to temperatures below 600° F. 

Extended elevated temperature exposure can embrittle 2205 stainless.

 

Corrosion Resistance

2205 duplex stainless steel is a cost effective solution for many applications where the 300

series stainless steels are susceptible to chloride stress corrosion cracking. Stress corrosion

cracking occurs when stainless steels are subjected to tensile stress, while in contact with

solutions containing chlorides. Increasing temperatures also increase the susceptibility of

stainless steels to stress corrosion cracking.

The combination of chromium, molybdenum and nitrogen convey the good resistance of 2205

to chloride pitting and crevice corrosion. This resistance is extremely important for services

such as marine environments, brackish water, bleaching operations, closed loop water systems

and some food processing applications. The high chromium, molybdenum and nitrogen contents

of 2205 provide corrosion resistance superior to common stainless steels, such as, 316L and 317L

in most environments.
