Nickel, Cobalt Alloys
ATI's nickel and cobalt alloys were developed to withstand severe service conditions. The nickel- and cobalt-based alloys known as superalloys are usually used at high temperatures where stainless steels have inadequate strength and/or oxidation resistance. Typical superalloy applications require materials that can withstand high stress and elevated temperatures for extended periods of time. Another group of Ni-based alloys has been designed primarily for use in highly corrosive environments where superior resistance to localized corrosion and stress corrosion cracking is needed.
