HASTALLOY
Commonly referred to as “Hastelloy” ® grade C276 developed by Haynes International. Perhaps the most popular nickel-based alloy, used in the widest variety of applications, including water treatment, chemical processing, and some nuclear reactor operations. Hastelloy is widely available in various types of flanges, fittings, valves, and other assembly components.
Other available grades known as or similar to Hastalloy are B2, G, X, and C22
A Nickel-Copper alloy developed by the International Nickel Co and authorized in 1906. This material is resistant to corrosion but more difficult to work with than other nickel alloys of the same family. Monel is commonly used in marine applications involving the perpetual corrosion of seawater and the development of accessories within assemblies handling corrosive material, such as strainers, wiring, valve gates, and fastener hardware.
Nickel-chromium alloys developed in the 1940s in the United Kingdom. They are commonly utilized in nuclear engineering, aerospace engineering, commercial refining, and other demanding large-scale applications. These materials have excellent resistance to corrosion and great strength even in high heat and stress utilization, making them excellent candidates for use in nuclear reactors and engine turbines.
Like its Inconel counterpart, these grades of nickel-chromium alloys have tight ranges on aluminum, titanium, and other trace element contents in order to produce material with the best properties in high heat applications. Commonly utilized in heat exchangers, power plants, furnaces, nuclear fuel processing, and other situations that involve corrosive media at high temperatures.
