Even in temperatures up to 2000° F, Alloy X nickel offers good strength and weldability, along with excellent oxidation resistance. It's often used for components in gas turbine engines and furnaces. This material is equivalent to Inconel HX and Hastelloy X.

This Alloy 22 nickel resists highly corrosive environments better than other nickel alloys such as 625 and C-276. It contains high amounts of chromium and molybdenum, which prevents it from oxidizing when exposed to hydrochloric, sulfuric, and nitric acid at high temperatures. This alloy won’t form stress cracks from sulfides in sour gas environments, and resists corrosion from alkalies such as sodium hydroxide and ammonium. It’s also better than stainless steel at preventing pitting from chemicals such as chloride. With crevice corrosion protection, it won’t corrode at gaps between surfaces. Alloy 22 nickel is easy to weld, and remains strong and corrosion resistant after welding and reshaping. This material is equivalent to Hastelloy C-22.
