Duplex Steel Plates are manufactured using a variety of alloying elements such as chromium, nickel, molybdenum and nitrogen. This allows for the development of a wide range of highly durable materials with excellent strength and corrosion resistance properties. The specific composition will depend on the grade chosen, but generally, Duplex Plates contain 23-27% chromium, 4-7% nickel, and 1-3% molybdenum. Nitrogen is also present in substantial amounts, which helps improve impact resistance and create a fine-grain structure that increases machinability and formability. When exposed to high temperatures, heavier plates can contain up to 0.25% copper to enhance their ability to withstand heat while maintaining structural integrity. Overall, duplex steel plates provide an economical solution when seeking an all-in-one combination of strength and corrosion resistance.
Duplex Steel Plates offer a range of beneficial properties that make them ideal for use in industrial settings. Notably, they have very high tensile and yield strengths, making them especially reliable under challenging conditions. Besides this, duplex steel plates are also highly corrosion-resistant, meaning they can retain their integrity in damp or abrasive environments. Furthermore, it is possible to easily machine and form these plates, allowing for the relatively simple customization of components made from them. For these reasons, duplex steel plates are often selected as the material of choice for many industrial applications.
Duplex steel plates have high environmental friendliness due to their superior corrosion resistance, excellent mechanical properties, and improved weldability. This makes them an ideal choice for environmentally conscious applications.
Grade Duplex Steel Plates can be identified by their superior mechanical, corrosion and fatigue properties compared to other ordinary steel plates. They are spectrally analyzed to ensure the presence of alloying elements like chromium, nickel, and molybdenum, which helps strengthen the material.
Duplex Steel Plates offer superior corrosion resistance, greater strength, and increased heat and pressure resistance - making them an ideal choice for a wide range of applications.
