Hastelloy G50 Alloy (UNS N06950) – Composition, Properties and Uses
Composition of Hastelloy G50 Alloy
The primary components of Hastelloy G50 alloy are nickel and chromium, which form the backbone of its corrosion resistance and mechanical strength. Nickel, being a naturally corrosion-resistant metal, serves as the alloy’s primary element, accounting for a significant proportion of its composition. Chromium, on the other hand, enhances the alloy’s resistance to oxidizing environments and contributes to the formation of a protective oxide film on the surface.
In addition to nickel and chromium, Hastelloy G50 also contains molybdenum, iron, cobalt, tungsten, carbon, manganese, silicon, sulfur, phosphorus, and copper. These elements are added in specific proportions to further enhance the alloy’s corrosion resistance, mechanical properties, and processability. For instance, molybdenum improves the alloy’s resistance to reducing environments, while cobalt and tungsten enhance its mechanical strength and high-temperature performance.
