GH3625 Nickel-Based Superalloy GH3625 Composition Properties Applications

GH3625 high-temperature alloy is a solution-strengthened nickel-based wrought superalloy primarily strengthened by molybdenum and niobium. It exhibits excellent corrosion resistance and oxidation resistance, good tensile properties, and fatigue performance from low temperatures up to 980°C, as well as resistance to stress corrosion in salt spray environments. As a result, it is widely used in the manufacture of aircraft engine components, aerospace structural parts, and chemical equipment.
