Inconel sheet, or called inconel plate, as a high-performance nickel-based alloy sheet, is widely used in many fields such as aerospace, chemical, oil and gas, and nuclear industries due to its excellent corrosion resistance, high-temperature strength, good processability and weldability.
Outstanding corrosion resistance: Inconel sheet has excellent corrosion resistance to a wide range of corrosive media, including oxidizing, reducing and neutral media. This corrosion resistance allows Inconel sheets to maintain their performance and integrity in harsh corrosive environments.
High Temperature Strength: Inconel sheet retains its high strength and toughness at high temperatures, making it ideal for use in high temperature environments. Its excellent creep and thermal fatigue resistance further enhances its reliability in high temperature applications.
Good processability and weldability: Inconel sheet is easy to process and weld, and can be made into desired shapes and sizes through a variety of processing methods. At the same time, it also has good weldability, can be connected by a variety of welding methods, and the performance of welded joints is equivalent to the parent material.
