MP35N SuperAlloy

Nickel Cobalt Bars (AMS 5844)

An age-hardenable superalloy stocked in round bars.


MP35N Nickel Bar

Ultra high strength quaternary superalloy.

MP35N is an age-hardenable superalloy that we stock in round bars and process in-house.


MP35N® is an age-hardenable quaternary superalloy containing nickel, cobalt, chromium, and molybdenum. The alloy combines ultra-high strength, toughness, and outstanding corrosion resistance. It may be used in the annealed condition but can easily be worked to tensile strength levels above 260 ksi (1793 MPa). The heat treatment process can raise the tensile strength by an additional 40 ksi (276 MPa).

Production Process

The VIM VAR melt process provides superior cleanliness and reduces the presence of non-metallic inclusions and residual elements. MP35N® alloy offers outstanding resistance to general corrosion, stress corrosion and crevice corrosion at all strength levels. The alloy resists corrosion in chloride solutions, salt water, hydrogen sulphide, and mineral acids (hydrochloric, nitric and sulphuric).

Stock Availability

We stock MP35N® bars in various sizes, which we process in-house to exact lengths for immediate supply.

Market Specific

We stock products to support specific target operating markets and their engineering applications.
