MP35N/UNS R30035/ W.Nr 2.4999/ AMS 5844


Introduction:

MP35N is a nickel-cobalt base alloy of the Multiphase alloy system that has a unique combination of properties-ultra high strength, toughness, ductility and outstanding corrosion resistance. The alloy is work-strengthened and aged to obtain strength levels of 260 to 300 ksi(1793-2068 MPa). MP35N alloy resists corrosion in hydrogen sulfide, salt water and other chloride solution, as well as the mineral acids(nitric, hydrochloric, sulfuric).In addition, it has exceptional resistance to crevice and stress corrosion cracking in sea water and other hostile environments.
