Ultra high strength, toughness & corrosion resistance

MP35N is a vacuum induction, vacuum arc, re-melted quaternary alloy based on nickel and cobalt with substantial additions of chromium and molybdenum.

The alloy possesses an unusually attractive combination of ultra high strength, toughness and outstanding corrosion resistance. MP35N alloy may be employed in the annealed condition but can easily be work strengthened to tensile strength levels in excess of 260 ksi (1,793 MPa) with the retention of good ductility. Aging of worked material causes precipitation hardening and can raise the tensile strength by an additional 40 ksi (276 MPa). The density of MP35N alloy is 8.43 g/cc.

Smiths High Performance offers MP35N from stock in bar, rod, wire, sheet, plate, strip and tubing. In-house processing options are also available.
