Duplex is a nonstandard and popular grade of stainless steel. It is very hard and difficult to manufacture. However due to low nickel composition, it is a cheaper alternative to high nickel based alloys. It must be only procured from trusted vendors.

The term Duplex is based on the concept that they have a two-phase microstructure consisting of grains of ferritic and austenitic stainless steel formulated in the same material. The term Super Duplex denotes high-performance Duplex steel based on elevated contents of chromium, nickel, and molybdenum to improve pitting corrosion resistance while additions of nitrogen promoted structural hardening, raising the yield strength and ultimate strength values without impairing toughness.

These stainless steels usually have a high level of Cr, always above 16%, a generally low content of Ni, 5-6%, accompanied by elements such as Mo, Si, Mn, Cu which endow them with a two-phase structure consisting of austenite and ferrite at room temperature. Hence, their name “two-phase” and “austeno-ferritic”.

Their mechanical properties at room temperature are higher than those of austenitic and ferritic steels and their resistance to corrosionis better than that of the ferritic steels and comparable, in an acid environment, with that of the austenitic grades; their resistance to corrosion by pitting and under stress is particularly high. Duplex stainless steels are about twice as strong as regular austenitic or ferritic stainless steels, have significantly better toughness and ductility than ferritic grades (although they do not reach the values of austenitic grades), have a range of corrosion resistance comparable to the range of austenitic stainless steels, have very good stress corrosion cracking resistance, and Duplex steels are cost-effective in a number of ways.

Their weldability is much better than that of the ferritic grades.

Duplex Stainless Steel Flanges can be manufactured and supplied in a variety of sizes and pressure ratings to meet project specific requirements of our customers. Our Duplex Stainless Steel Flanges and fitting products are widely supplied to many industries including boiler manufacturing, brewing tanks, and desalination plants.

Duplex Stainless Steel Flanges and duplex fittings are generally lower in cost, as the lower percentage of alloying element is used in the manufacture of duplex stainless steel. The yield strength of duplex stainless steel products is higher compared to austenitic stainless steel products, as a result of which users can purchase relatively lower thickness duplex pipes and duplex fittings.

Know more about Duplex Stainless Steel

Duplex Stainless steel is a variant of stainless steel in which high levels of chromium, nickel and molybdenum help improve pitting corrosion resistance. The presence of nitrogen help in structural hardening, increasing the yield strength and ultimate strength, without altering the toughness. Duplex stainless steel consists of grains of both ferritic and austenitic stainless steel. Embedded in the same material. It is generally tougher than ferritic steel and has strength almost double of that of austenitic steel. It has excellent corrosion resistance. It successfully combats intergranular corrosion. It also prevents stress corrosion cracking in chloride and sulfide environments.

Chemical Composition

Duplex stainless steel has better ductility than ferritic steel. It cannot be hardened by heat treatment, but can be work hardened. It can also be welded easily using all the standards methods of welding. Post weld distortion and residual stresses are reduced on account of low thermal expansion.
This variant of stainless steel has a wide range of applications. It is used by the chemical processing industry for transportation and storage purposes. It is also used by the oil and gas plants and offshore rigs. It is also used in the oil and gas refineries. Due to resistance to stress corrosion cracking in the presence of chloride ions, it is suitable for use in marine environments. The pulp and paper industry also uses Duplex stainless steel. Moreover, it is used in pollution control equipment.

All Duplex Stainless Steel Flanges are offered with an NACE 3.1 Certification, Mill Test Certification and ISO 17025 Standards by a Government of India approved Laboratory. Positive Material Identification is done on all raw material procured at Kinnari Steel.

What are the problems that you are likely to face?

The customers fall into the trap of greedy suppliers. They end up paying huge sums for the services they never receive. The alloys are often unavailable at the time of the order. They have to wait for months before the alloys are supplied. Also, the supplied alloys are never up to mark. The alloys have the poor surface finish and they tend to yield under high pressure. Also, on account of poor packaging, they get influenced by the environment and get degraded. The materials are often inconsistent with ASTM standards. Sometimes, they are supplied rejected material without proper processing. Sometimes, to worsen the situation, wrong grades are supplied, which leads to high rejection rates. After the delivery of products, the suppliers no longer hold responsibility regarding the after sales services. Ultimately the customer is the sufferer in this vicious circle.
