Technical Information for MP35N

MP35N is a multi-phase, cobalt-base alloy offering a unique combination of ultra-high strength, toughness and corrosion resistance.


MP35N alloy is a nonmagnetic, nickel-cobalt-chromium-molybdenum alloy possessing a unique combination of ultrahigh tensile strength (up to 300 ksi [2068 MPa]), good ductility and toughness, and excellent corrosion resistance. In addition, this alloy displays exceptional resistance to sulfidation, high temperature oxidation, and hydrogen embrittlement. 

Applications of MP35N

  • Structural components on the Space Shuttle
  • Airframes
  • Tie rods
  • Petrochemical equipment
  • Submersibles
  • Marine equipment
  • Leading edge strips
  • Any other situation where high strength and good corrosion resistance are the most extreme demands.
