Inconel is a heat-resistant and corrosion-resistant nickel-chromium-iron alloy, a nickel-based alloy. This alloy is a solid solution strengthened nickel-based deformed high-temperature alloy with molybdenum and niobium as the main strengthening elements. It has excellent corrosion resistance and high oxidation properties, good tensile properties and fatigue properties from low temperature to 980°C, and is salt resistant. Stress corrosion in fog atmosphere. Therefore, it can be widely used in manufacturing aerospace engine parts, aerospace structural components and chemical equipment.

Commonly used grades include Inconel 625, Inconel 600, Inconel 601, inconel 718, inconel x750, etc
