EN 10028-4 Nickel Alloy Steel Plates for Pressure Vessel
EN 10028-4 Nickel Alloy Steel Plates are high-performance materials explicitly designed for pressure vessels, offering superior strength, toughness, and corrosion resistance in extreme conditions. These plates are part of the EN 10028-4 standard, which covers flat products made of weldable, fine-grain steels, and are particularly suited for applications requiring excellent low-temperature performance, such as cryogenic storage tanks, offshore oil and gas platforms and chemical processing equipment. Including nickel in the alloy enhances the steel’s durability and resistance to brittle fracture, making it an ideal choice for pressure vessels operating under high pressure and in corrosive environments. With their exceptional mechanical properties and reliability, EN 10028-4 Nickel Alloy Steel Plates ensure long-term safety and efficiency in some of the most demanding industrial applications.
