Uses of Duplex Stainless Steel in Industry

Duplex stainless steel is a type of alloy composed of ferrite and austenite. It is known for its high strength, corrosion resistance, and heat resistance. This makes it an ideal material for use in various industries, from food processing to marine engineering. Let’s take a look at some of the most common applications of duplex stainless steel.

Food Processing

Duplex stainless steel is commonly utilized in food processing because it has superior corrosion resistance when compared to other materials. This means that it can withstand contact with acidic foods and liquids without reacting or corroding, thus ensuring the safety and quality of the food products being processed. In addition to its corrosion resistance, duplex stainless steel is easy to clean and sanitize, further increasing its desirability for food processing plants.

Marine Applications

The high strength and corrosion resistance combination also make duplex stainless steel an ideal choice for marine applications such as shipbuilding and offshore oil rigs. The high strength ensures that these structures can withstand even the harshest weather conditions while providing excellent levels of stability and protection against corrosion. Additionally, duplex stainless steel can be used in underwater vessels such as submarines due to its excellent heat resistance properties, allowing the vessel to remain submerged for extended periods without suffering any damage or degradation.

Chemical Plants

Duplex stainless steel is often used in chemical plants due to its ability to resist corrosion caused by harsh chemicals such as acids and alkalis. Its high strength also allows it to be used where mechanical stresses are present, making it ideal for components that must endure high pressure or heavy loads regularly. Furthermore, its heat-resistant properties make it suitable for use in hot areas where conventional materials may not be able to handle the extreme temperatures without failing.


Duplex stainless steel is an incredibly versatile material with many uses across a wide range of industries. From food processing plants and chemical plants to marine engineering projects, this type of alloy provides superior performance levels when compared with other materials thanks to its combination of high strength, corrosion resistance, and heat resistance properties. For anyone looking for a reliable material that can perform under tough conditions without sacrificing quality or safety, duplex stainless steel should be at the top of their list!
