Nickel cobalt base alloy AMS 5844 MP35N
HY MP35N Material grades and equivalents
MP35N/UNS R30035/ W.Nr 2.4999/ AMS 5844
Introduction:
HY 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). HY 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.
