Hastelloy C4, 2.4610, N06455, Nickel Alloy Spring Wire
This Nickel-Chromium-Molybdenum alloy tolerates high temperatures and gives a design freedom in areas where weld geometry makes excessive heat build-up unavoidable. Resistance to general and localised corrosion and stress corrosion cracking is generally similar to Hastelloy C-276. With its high contents of Chromium and Molybdenum, Hastelloy C4 is able to withstand both oxidizing and non-oxidizing acids, and is resistant to pitting and crevice attacks in the presence of chlorides and other halides. Like other nickel alloys, Hastelloy C4 is ductile, easy to form and weld.
Hastelloy C4 is also known as Nicrofer 6616.
