Containing titanium and aluminum for added hardness, K-500 nickel has double the yield strength of 400 nickel, with the same excellent corrosion resistance. Because it withstands highly corrosive environments, it’s often used in propeller shafts, ship hardware, and valves and regulators in the oil and gas industries. It also resists chloride stress corrosion better than stainless steel. Unlike 400 nickel, K-500 nickel is nonmagnetic, so it won’t damage electronics.

C-276 nickel has excellent corrosion resistance against chemicals, including nitric acid, sulfuric acid, and hydrochloric acid. It resists chloride pitting better than stainless steel does, so it’s often used around bleach in paper manufacturing. This alloy won’t stress crack from contact with sulfides, making it good for use in petrochemical applications. C-276 nickel is easy to weld and remains corrosion resistant after welding. It retains its strength after being reshaped. C-276 nickel is comparable to Hastelloy C-276.

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.
