Features
GH3625(GH625) alloy is a solid solution strengthened nickel-based deformed superalloy with molybdenum and niobium as the main strengthening element. It has excellent corrosion resistance and oxidation resistance. It has good tensile and fatigue properties from low temperature to 980 degrees Celsius, and is resistant to stress corrosion under salt spray atmosphere.

The chemical composition of the alloy is divided into three categories: standard components, high quality components, high purity components. High-quality components reduce carbon and increase niobium on the basis of standard components, thereby reducing the amount of niobium carbide, reducing the number of fatigue sources and strengthening phases, improving the content of fatigue resistance, and improving the purity and comprehensive performance of the material.
