MP35N (UNS R30035)

MP35N (UNS R30035) is an age hardenable Nickel-Cobalt base superalloy that has a unique combination of properties – ultra high strength, toughness, ductility and outstanding corrosion resistance. MP35N resists corrosion in hydrogen sulfide, salt water and other chloride solutions. It also has excellent resistance to crevice and stress corrosion cracking in sea water and other hostile environments. Suitable where a high combination of strength, high modulus values and good corrosion resistance are required.
