MP35N is an age hardenable Nickel-Cobalt base alloy that has
a unique combination of properties - ultra high strength,
toughness, ductility and outstanding corrosion resistance.
MP35N resists corrosion in hydrogen sulphide, 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.
Applications include:
- Medical Devices
- Marine Engineering
