Inconel625 alloy is a solid solution strengthened nickel-based deformed superalloy with molybdenum and niobium as the main strengthening elements. It has excellent corrosion resistance and oxidation resistance. It has good tensile and fatigue properties from low temperature to 980℃, and is resistant to stress corrosion under salt spray atmosphere. Therefore, it can be widely used in the manufacture of aerospace engine components, aerospace structural components and chemical equipment. The alloy is used to make parts such as engine casings, guide blades, mounting edges and barrels, and fuel pipelines.
