MP35N™ – High Strength Corrosion Resistant Metal

MP35NMP35N™ is a nickel-cobalt alloy which provides a unique combination of properties including ultra-high strength, toughness, ductility, and outstanding corrosion resistance, being used for fasteners and components in the medical, aerospace, and oil and gas industry.


MP35N™ Specification and Stock:

High Strength option:

  • AMS 5844 – solution treated and cold drawn bars
  • AMS 5845 – solution heat treated, cold drawn and aged bars

CRA option:

  • NACE MR 01-75 – sulphide stress cracking resistant material for oil field equipment

Fastener standard:

  • AMS 7468 – bolts and screws, forged head, roll threaded after ageing

We hold stock from 12.7 mm (1/2”) to 76.2 mm (3”), mainly in the optimum SCC (NACE) condition, along with selected smaller sizes of AMS material. Material can also be supplied as cold drawn tubing on a leadtime.

Broder Metals provide MP35N with our global same day quote / next day despatch service. All of our metals are fully traceable for your confidence, with clear certification delivered electronically or sent with the material as requested.

The high strength variant of MP35N™ is used in the medical and aerospace industry while material produced for optimum corrosion resistance properties is primarily used in the oil & gas industry.

Applications include:

  • fasteners
  • springs
  • non-magnetic electrical components
  • instrument parts
  • valve components
  • high pressure door fittings
  • actuators
  • seals
  • shafts and other components.

Because of its corrosion resistance, MP35N™ is used in harsh environments such as hydrogen sulphide, salt water and chloride, as well as in mineral acids (nitric, hydrochloric and sulphur). The material has exceptional resistance to crevice and stress corrosion cracking in sea water and other hostile environments.
