Additionally, duplex 1.4462 plates exhibit high strength, which allows them to withstand heavy loads and pressure. This makes them ideal for structural components in various industries, including construction, transportation, and manufacturing.
Moreover, these plates have good weldability, meaning they can be easily welded without sacrificing their corrosion resistance or mechanical properties. This allows for the fabrication of complex structures and components, further expanding their utility.
The composition of Duplex Steel EN1.4462 Plates also imparts excellent toughness and ductility, ensuring they can withstand impact and deformation without fracturing. This makes them suitable for applications where durability and reliability are critical, such as in the production of pressure vessels, storage tanks, and heat exchangers.
Furthermore, duplex stainless steel 1.4462 plates exhibit good resistance to stress corrosion cracking and pitting corrosion, further enhancing their longevity and performance in aggressive environments. In terms of physical properties, these plates typically have a density of around 7.8 g/cm³ and a specific heat capacity of approximately 460 J/kg·K. They also have a thermal conductivity of about 14 W/m·K, allowing for efficient heat transfer in various applications.
