Duplex stainless steel was developed as a product which could improve upon some of the technical weaknesses of the standard austenitic and ferritic stainless steels that are available in the market. Both have low strength, ferritic steels have poor low temperature toughness, and austenitic steels have a very low resistance to stress corrosion cracking. Duplex stainless has a microstructure which is split roughly 50:50 between austenite and ferrite and balancing of these phases provides the following benefits:

  • Higher strength which is around twice that of Type 304 austenitic stainless steel. This leads to reduced plate thicknesses being used in fabrications reducing the weight which is of particular significance in items such as pressure vessels, storage tanks, and structural applications such as bridges.
  • Good weldability in thick plates.
  • Good low temperature toughness.
  • Resistance to stress corrosion cracking of importance in many applications including hot water tanks, process plant, brewing tanks, and desalination plant.

It is worth noting that Duplex stainless steels are still being developed and improved by steel makers.

Another key feature of Duplex stainless is its enhanced corrosion resistance. There is no single measure of corrosion resistance but the Pitting Resistance Equivalent Number (PREN) is widely used as a means of comparing the relative corrosion resistance of different steel grades. The PREN is obtained by applying a mathematical formula to the chemical composition of a steel so that PREN = %Cr + (3.3 x %Mo) + (16 x %N). Using this formula 31803 Duplex stainless has a PREN of 35 which when compared with the PREN of Type 304 and Type 316 (18 and 24 respectively) demonstrates its superior corrosion resistance.

In short, due to its higher strength, longer component life cycle, and lower alloy composition, Duplex stainless can be a very cost effective solution to an engineering problem.

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

General Duplex stainless steel information

2205 is the most widely used duplex (ferritic/austenitic) stainless steel grade. It finds applications due to both excellent corrosion resistance and high strength. The standard duplex S31803 composition has over the years been refined by many steel suppliers, and the resulting restricted composition range was endorsed as UNS S32205 in 1996. Duplex S32205 gives better guaranteed corrosion resistance, but for much of the Duplex S31803 currently produced also complies with Duplex S32205. 2205 is not generally suitable for use at temperatures above 300ºC as it suffers from precipitation of brittle micro-constituents, nor below -50ºC because of its ductile-to-brittle-transition.

Duplex Applications

Chemical processing, transport and storage, Oil and Gas exploration and processing equipment, Marine and other high chloride environments, Pulp and paper digesters, liquor tanks and paper machines.

Duplex Corrosion Resistance

Excellent general corrosion resistance; superior to Grade 316 in most environments. Excellent resistance to localized corrosion including intergranular, pitting and crevice corrosion; the CPT of 2205 is generally at least 35ºC. The grade is also resistant to chloride stress corrosion cracking (SCC) at temperatures of up to about 150ºC. Grade 2205 will often perform well in environments which cause premature failure of austenitic grades. It has better resistance to sea water then Grade 316.

Duplex Heat Resistance

Although 2205 has good high temperature oxidation resistance, this grade - like other duplex stainless steels - suffers from embrittlement if held for even short times at temperatures above 300ºC. If embrittled, this can only be rectified by a full solution annealing treatment. Duplex stainless steels are almost never used above 300ºC.

Duplex Heat Treatment

Solution treatment (annealing) - heat to 1020ºC-1100ºC and cool rapidly. This grade cannot be hardened by thermal treatment, but does work harden.
