Nickel AlloysAMS5844-5/AMS5758 (MP35N) Bar & Sheet

An age hardenable nickel-cobalt base alloy with a unique combination of properties.

MP35N is a ultra-high strength nickel-cobalt alloy, with good ductility, oxidation and corrosion resistance which is hardened through work hardening and ageing.

It is a non-magnetic alloy that offers excellent tensile strength, good ductility, toughness and excellent corrosion resistance. The alloy is work-strengthened and aged to obtain strength levels of 260 to 300 ksi (1793-2086 MPa) in its full strength and stress corrosion cracking resistance (SCC) for harsh environments.

MP35N alloy resists corrosion in hydrogen sulfide, salt water and other chloride solutions, as well as the mineral acids (nitric, hydrochloric, sulphuric). In addition, it has exceptional resistance to crevice cracking in seawater and other hostile environments.
