Duplex Stainless Steel Properties

Duplex stainless properties are that they are work hardenable and highly resistant to corrosion. Duplex steel has inbuilt composition of both ferritic and austenitic stainless steels; therefore, it displays the characteristic and properties of both these steels. Due to this combination, duplex stainless steel is much tougher than the normal ferritic stainless steel or the austenitic stainless steel. Duplex stainless has the ability to resist cracking under stress corrosion, which is not seen in the other general types of stainless steel. The magnetic property of duplex stainless is uncommon in the other austenitic types of SS.

Duplex Stainless Steel Composition

Duplex stainless steel composition varies, based on the kind of duplex alloy. Duplex stainless steels have properties that are characteristic of ferritic stainless steels and also of austenitic stainless steels. Generally, duplex stainless steels are tougher than ferritic stainless steels. These material have a corrosion resistance that is far greater than most of the other grades of stainless steel that are in common use, such as 316, 304, etc. The basic idea of creating duplex stainless steels, was to create a product, that is a mixture of both austenite and ferrite stainless steels.

Their features made them very attractive compared to equivalent Super Duplex Austenitic grades:

  • higher resistance to Stress Corrosion Cracking,
  • higher mechanical properties
  • and lower alloy cost.

Duplex Steel Grades

There are many duplex steel grades such as Duplex 2304, which is also referred to as lean duplex grade. 2304 duplex steel grade has high resistance to stress corrosion splitting, fine weldability, first-rate machinability, high thermal conductivity, elevated mechanical strength, etc. 2507 ss super duplex grade has elevated molybdenum, chromium and nickel levels, hence it offers a tremendous resistance to pitting and general corrosion. LDX2101 Stainless Steel has the same amazing properties as the others and it is mainly used as it too shows tremendous strength, durability and cost efficiency.

Duplex stainless steel grades are the largest used stainless steel grade. Characteristic of duplex stainless steels are their high yield strength, which is twice more than standard austenitic stainless steel grades. Duplex stainless steels are in demand because of their price stability, their better resistance to corrosion, their higher strength and their lower price. There are many grades of duplex stainless steels and some of them are S32520, S32001, S31803, S32205, S32304, 4404, 2304, 4501, 4521, LDX 2101, 254 SMO, 2507 and 4301. Duplex stainless steels can very easily be differentiated from other austenitic grades of stainless steel, as they are magnetic.

Super Duplex Steel Grades

Super duplex steel grades are S31200, S32760, S31260, S32900, S32550, S32950 and S32750. Super duplex stainless steel microstructure is a mixture of ferrite and austenite components. Super duplex stainless steel is a very tough and sturdy duplex steel, which is highly corrosion resistant. Because of the microstructure, super duplex stainless steel warranties a high resistance to pitting and stress corrosion cracking, compared to the other general stainless steels. The chemical composition of super duplex stainless steel has high levels of molybdenum, chromium and nickel, with some addition of nitrogen, to increase the ultimate and yield strengths.

Duplex Steel Density

Duplex steel density is 7.8 g/cm3. The Thermal Expansion of duplex stainless steel is 11 m/μm/°C. The Electrical Resistivity of duplex stainless steel is 8.12 μohm/cm. The Thermal Conductivity of duplex stainless steel is 15 W.m -1.°K-1. The Chemical Composition of duplex stainless steel is Cu is 0.5 min. and 1 max., C is 0.03 max., N is 0.24 min. and 0.35 max., P is 0.35 max., Mn is 2 max., Mo is 3 min. and 5 max., Si is 1 max., Ni is 6 min. and 8 max., Cr is 24 min. and 26 max., and S is 0.015 max.

Duplex Stainless Steel Market

The duplex stainless steel market is huge, as there is a big demand for this material, all over the globe, because of its properties. Duplex stainless steels are resistant to stress corrosion cracking. Duplex stainless steels have a metallurgy that is far more complex as compared with ferritic steels or austenitic steels. The most in demand duplex stainless steel is 2205, because of its high strength and superb resistance to corrosion. The name of grade 2205 stainless steel is derived from the fact that it contains 22% Chromium and 5% Nickel. There is a lot of marketing activity that surrounds duplex stainless steel and all the time, new grades are being declared.
