Alloy Wire International

Datasheet: MP35N

MP35N

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.

The four alloy elements in MP35N are the basis for corrosion resistance in almost every Stainless Steel, Nickel and Cobalt-based alloy commonly used in the industry. The alloy resists corrosion in hydrogen sulphide, salt water and other Chloride solutions, as well as the mineral acids (Nitric, Hydrochloric and Sulphuric).

MP35N is 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.
