In a country like India, the industrial sector is very diversified, and the demand for new and sturdy materials is very high all the time. The frequent corrosion issue is the biggest headache for the industry today.
The corrosion of coastal infrastructure, chemical processing units, oil and gas installations, and water treatment plants can be very expensive to repair. This can also lead to the malfunctioning of the whole system, and endanger human life.
This is the point at which duplex stainless steel is creating a real impact. Having remarkable strength, durability, and corrosion resistance, duplex stainless steel has become the best corrosion resistant material for industrial use.
Corrosion is a natural process in which metals interact with their surroundings. In India, this problem is a big one because the country has a big coast and a humid climate, also there are polluted urban areas and there is constantly growing industrial activity. Buildings situated in coastal regions such as Mumbai, Chennai, and Kochi are under constant onslaught of salt-laden air, which is the main cause of more accelerated rusting and materials’ damage.
Conventional materials such as carbon steel, when economical, are not durable in such an environment. Even common quality stainless steels with sufficient corrosion resistance can get corroded quickly in severe industrial or marine environments. This makes the engineers and manufacturers switch to more reliable options and one of them is duplex stainless steel.
Duplex stainless steel is one of the stainless steel grades that comes with two distinct microstructures namely; austenitic and ferrite. This bistable structure has a combination of the properties. It has higher strength and much more improved resistance to local and bulk corrosion compared to the regular type of stainless steel.
The most significant benefits of duplex stainless steel include its capability to prevent stress corrosion cracking caused by chlorides. This makes them perfect for use in marine environments, desalination plants, and chemical factories, where the materials need to be resistant to aggressive chemicals and salty water.
Due to its high resistance to corrosion, duplex stainless steel has the capability of standing firm against abrupt changes in temperature and pressure. Thereby it is one of the most common materials implemented in heat exchangers, pressure tanks, and pipes.
In India, a multitude of industries have started using duplex stainless steel because it is highly efficient and more economical in the long run. The offshore areas of the oil and gas sector, which face rough conditions, have made good use of duplex steel for offshore installations. At the same time, the water treatment sector has a fondness for it due to its capacity to handle chlorinated and acidic water without undergoing any corrosion process.
For building the maritime infrastructure such as bridges, harbors, and power stations, duplex stainless steel has indeed emerged as the best corrosion resistant material.
Despite the fact that duplex stainless steel has a higher initial price when compared to standard steel, its long-term advantages are difficult to ignore. This is because its ability to resist corrosion can in return mean that the requirement of frequent repairs or replacements is substantially cut down.
Duplex stainless steel also has the potential to create fewer unwanted incidents and problems for workers and the surroundings. When taken from a lifecycle point of view, duplex stainless steel is by far the best corrosion resistant material for use in India, due to its wide range of potential applications for many different industries.
The increasing demand for products that can work effectively in very tough conditions is being felt all over Indian industries. Corrosion is not just a matter of maintenance anymore. It is also a point where safety, performance, and profit are the ones affected. As India is furthering investment in infrastructure, energy, and manufacturing, the request for lasting and sustainable materials will only increase.
Duplex stainless steel tops the list when it comes to addressing such needs. It provides the best option for engineers and project managers due to its outstanding durability, good performance for a long time, and excellent corrosion resistance. The duplex stainless steel has a range of properties that make it suitable for all kinds of industrial applications.
