MP35N® Nickel Bar

Ultra high strength quaternary superalloy.


MP35N provides outstanding resistance to general corrosion, stress corrosion and crevice corrosion.

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


MP35N® is an age hardenable quaternary superalloy with nickel, cobalt, chromium, and molybdenum. The alloy possesses a combination of ultra high strength, toughness and outstanding corrosion resistance. MP35N® alloy may be used in the annealed condition but can easily be work strengthened 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).
