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.

Comparable to Hastelloy C276, these balls resist corrosion from harsh chemicals, such as nitric acid, sulfuric acid, and hydrochloric acid. They’re often used in bearings and valves. They won’t stress crack from contact with sulfides, making them good for use in petrochemical applications. This nickel alloy resists chloride pitting better than stainless steel, and it’s more corrosion resistant than nickel K500.
