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 for this alloy also include medical devices and dental products.
Combination of high strength, ductility and good mechanical properties at ambient temperatures Excellent corrosion resistance in hydrogen sulphide Excellent resistance to crevice and stress corrosion cracking in sea water Age hardenable (Spring Temper only)
