Duplex alloys

Duplex steel is becoming increasingly popular in various industries. It combines the advantages of austenitic and ferritic steel, which provides high strength and corrosion resistance. These characteristics have made the material popular, and its production has begun to grow rapidly. Today, duplex alloys are used in construction, equipment manufacturing, shipbuilding, and other areas.

How did this material appear on the market?

Initially, duplex alloys were developed in the forties of the last century. However, they have become widely used only in recent decades. The main factor that contributed to the spread of these materials was the improvement of production technologies. Today, manufacturers can precisely control the nitrogen content of alloys, which makes it possible to create high-quality products with excellent characteristics.

Advantages of duplex steel

Duplex steel offers a number of significant advantages:

• It has high strength, which allows it to be used in various structures that can withstand heavy loads. The material’s strength is 400-450 MPa, which is twice that of a pure ferrite or austenitic alloy. This makes it possible to significantly reduce the consumption of raw materials and reduce the thickness of the metal, which is important in industries such as construction and shipbuilding.
• Another important advantage is its excellent corrosion resistance. Duplex steel combines the best properties of two types of steel, which makes it resistant to corrosion processes even in aggressive environments. This property is especially valued in industries such as the petrochemical, gas and food industries, where the material is constantly exposed to water and chemicals.
• In addition, duplex steel has excellent impact strength. This material tolerates low temperatures better than other alloys, making it ideal for use at temperatures down to -80°C. Unlike other materials, duplex steel is resistant to corrosion cracking, which is important for equipment exposed to water or chemicals.
• Duplex steel is also beneficial in terms of resource savings. Thanks to its high strength and corrosion resistance, it is possible to reduce wall thickness and weight, which significantly reduces material and transportation costs while maintaining the strength and durability of products.

These advantages make duplex steel an ideal choice for various industries. The key is to buy it from a trusted source. You can order it from us with a guarantee of quality and dimensional compliance with all modern standards. The price will definitely be as favorable as possible.

Application in welding

Welding duplex steel requires compliance with several important rules. In order to avoid problems when joining metals, it is necessary to carefully prepare the surfaces by removing dirt and rust, and to ensure the correct welding temperature. To protect the welds from corrosion, special mixtures of gases such as hydrogen and nitrogen combined with argon are used.

Features of super-duplex and hyper-duplex alloys

To improve corrosion resistance, additional elements such as nickel are added to duplex alloys. This makes it possible to create super-duplex and hyper-duplex alloys that are even more resistant to corrosion and can be used in more aggressive environments. These materials are used in the chemical industry, in the production of a wide variety of food products, and in medicine.
