MP35N is a registered trademark of SPS Technologies Inc.

MP35N is a non-magnetic Nickel-Cobalt-Chromium-Molybdenum Alloy. This unique combination of properties enables ultra high strength, toughness, good ductility and excellent corrosion resistance. MP35N also has exceptional resistance to sulfidation, high temperature oxidation and hydrogen embrittlement. MP35N is used in a wide variety of applications from fasteners, springs, nonmagnetic electrical components, instrument parts in medical, seawater, oil and gas well, and chemical and food processing environments.
