Brief introduction:
MP35N(UNS R30035) belongs to high-strength multiphase cobalt based high-temperature alloys and is a material grade for fasteners developed by SPS Technologies, a manufacturer of space shuttle fasteners in the United States. MP35N is one of the few alloys used in extreme environments with high-strength grades, and it does not undergo stress corrosion cracking.
MP35N alloy is mainly used in the production of fasteners and springs, and is used in aerospace space equipment, cruise missile launch devices, heart pulsators, valves for nuclear devices, as well as parts working in chloride media in the petroleum industry and shipbuilding industry.
