CWI Nickel Prime Series MP35N® is a multi-phase, nickel-cobalt based alloy that has a unique combination of ultrahigh tensile strength, good toughness, and excellent corrosion resistance.
MP35N® is a true superalloy: it maintains its toughness, ductility, and corrosion resistance in a range of environments from cryogenic temperatures up to 850°F (454°C), and is virtually immune to crevice and stress corrosion. MP35N® is highly resistant to sulfide stress corrosion cracking and provides excellent performance in the most demanding sour well environments, making it a highly sought-after alloy for oil & gas extraction. It’s a preferred choice for jobs and applications like medical devices, aerospace engines, and springs.
Commercial use of the alloy is governed by industry standards such as: AMS 5844, 5845 (capable), ASTM F562, NACE MR0175 (ISO 15156-3), NACE MR0103 (ISO 17945)
Aerospace use is supplied via AMS 5678G which further controls the material with additional qualification tests on the final drawn wire’s microstructure.
