MP35N R30035 Nickel-Cobalt base superalloy used for fasteners and Springs
MP35N 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.

The ability of MP35N® to resist stress-corrosion and crevice corrosion often leads to to its selection as a fastener material, although its uses also include petrochemical equipment, racing engines and submersibles as well as medical devices and dental equipment. This alloy is typically work-strengthened and aged to obtain strength levels of 260 to 300 ksi.
