N06625 Nickel Alloy Clad Plate
The Nickel-based alloy 625 clad plate is made from Nickel-based alloy 625 and carbon steel or low-alloy steel through a composite process, combining the exceptional corrosion resistance of alloy 625 with the strength and cost-effectiveness of the base steel. Nickel alloy 625 (Inconel 625) meets ASTM B443/B444 UNS06625 and Japanese NCF625 standards .It contains high levels of chromium and molybdenum, providing resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride, acidic, and seawater environments. It also maintains strength and oxidation resistance at high temperatures, suitable for use in conditions up to 980°C. As the base material, carbon or low-alloy steel offers robust structural support, significantly reducing overall material costs.
This clad plate is typically produced using explosion welding, hot-rolling, or a combination of explosion and rolling processes to form a high-strength, stable bonded interface. The Nickel alloy 625 composite plate combines high corrosion resistance and economic efficiency, making it suitable for use in marine engineering, oil and gas, and chemical equipment, where high corrosion resistance and high-temperature, high-pressure durability are essential. Typical applications include oil and gas pipelines, chemical storage tanks, reactors, desalination equipment, and nuclear reactor components, providing reliable, long-lasting material solutions for extreme environments.
