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

Chemical Element % Present
Carbon (C) 0.0 – 0.03
Chromium (Cr) 21.00 – 23.00
Manganese (Mn) 2.00 max
Silicon (Si) 1.00 max
Phosphorous (P) 0.0 – 0.03
Sulphur (S) 0.0 – 0.02
Nickel (Ni) 4.50 – 6.50
Nitrogen (N) 0.08 – 0.20
Molybdenum (Mo) 2.50 – 3.50
Iron (Fe) Balance

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.

The grief of the consumer today

In the ever increasing competition, it is the quality of goods and services that is degrading at an alarming rate. It affects no one but the customer. The customers find themselves struggling with high commission, and poor quality of the supplied material. They are often lost after the delivery of products, as they have no one to attend to their after sales grievances. There are often no mill reports to guarantee the good quality of products. The material is often very hard to be put to use and yields under high pressure. The goods take forever to be delivered and when they are, they tend to lose their economic value on account of poor, unprofessional packaging. Sometimes, to worsen the situation, wrong grades are supplied. Scrap material is supplied without proper treatment. That often leads to increase in rejection rates. There is no control on quality and testing. The growing distress amongst the consumer is an example of the darker side of the market. In the midst of false claims and promises, it is the customer who ends up in severe losses.
