Duplex Steel Sheets

Duplex steel are a double layer Steel which contains Chromium and nickel on the upper layer and only chromium in the lower layer. Because of this double layer property, Duplex Steel is known for its Corrosion resistance property. It can even be a substitute of the Austenitic grade of the marine surrounding. The Stress Corrosion Cracking, which is due to Chloride is also taken care by Duplex. Corrosion which takes place in intergranular and crevice spaces of the Steel is also taken care by the Duplex Steel Sheet because of the double layer.
It shows good thermal resistance and can be wielded by most Standard methods, so having the technical problem is very minor in case of Duplex Steel Sheets. Duplex Steel Sheets Manufacturers has much application because of its double layer property. The double Layer also offers greater Strength and highest stress corrosion cracking when compared to other Steel.

Duplex steel consists of the combination two microstructure called the austenite which 304 and ferrite which is 430 ,layers which increase its commercial demand as its application also increases. If we consider Duplex steel in the top layer it contains chromium and nickel and in the bottom layer, it has only chromium. The presence of Nickel helps the chromium to enhance its properties.
Double layer also helps it to be corrosion resistance, thermal resistant, Stress Corrosion Cracking, which is due to Chloride is also taken care by Duplex. Corrosion which takes place in intergranular and crevice spaces of the Steel is also taken care by the Duplex Steel Sheet because of the double layer.
The two main advantage of this type of material is the presence if nickel and the double layer which increases its commercial demand than any other steel or alloy available in the market so the client should choose its supplier properly.

Typical Applications of Duplex Steel Sheets Include :

  • desalination plants
  • heat exchangers
  • Marine applications
  • oil and gas exploration
  • chemical processing
  • processing equipment
  • storage and transportation units
  • Pulp and paper digesters
  • liquor tanks
  • paper machines

Duplex Steel is one of the most diverse alloy family product. It is available in many forms. Its pricing depends on the type of alloy our customer selects. It is usually cheaper compared to other alloys which usually have high chromium content and other expensive metals to enhance their properties. We make Duplex Steel Sheets Suppliers according to the specification given by our client. Price of Duplex Steel Sheets will vary depending upon the specifications and mechanical properties.

The Processing of steel carp and alloy together leads to the production of Inconel Steel. The amount of Alloy mixed decides the capability of the Steel works.

But still they are following steps:

1. Step one is to melt the metal including alloy and non-alloy into an electric arc furnace and later on adding the chemical energy like carbon, ferrosilicon, oxygen or fuel gas mixtures to speed up the process

2. After the melting process is done. The melts still is further processed in AOD which is Argon-Oxygen Decarburization. In which the carbon content is reduced and the mixture of Argon and Oxygen is added.

3. If we need low amount of Argon and oxygen then melted steel is added to the VOD which is Vacuum Oxygen Decarburization. And then melted steel is poured on the ladle
