UNS R30035/MP35N bars

UNS R30035/MP35N

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). 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.

    UNS R30035/MP35N alloy has the following characteristics:

    • MP35N alloy is a non-magnetic nickel-cobalt-chromium-molybdenum alloy with unique ultra-high tensile strength (up to 300ksi[2068MPa], good ductility and toughness and very good corrosion resistance. In addition, the alloy It also shows extraordinary resistance to vulcanization, high temperature oxidation and hydrogen embrittlement.

    Corrosion resistance of UNS R30035/MP35N:

    • MP35N has good resistance to sulfuration, high temperature oxidation, crispness, salt spray and most mineral acids. The alloy has excellent resistance to stress corrosion cracking under severe environments (-200 to +315) and high strength. The alloy also has extremely high resistance to local corrosion, such as pitting and crevice corrosion.

    UNS R30035/MP35N application areas:

    • MP35N alloy can be used for fasteners, springs, non-magnetic components and instrument parts in medical, seawater, oil and gas well, chemical and food processing environments.
