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 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. Ageing 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.
MP35N® is a multi-phase alloy containing Nickel, Cobalt, Chromium and Molybdenum with a unique range of properties - ultra high strength, toughness, biocompatibility and corrosion resistance. It is produced by vacuum induction melting and vacuum arc re-melting (VIM-VAR) and is then strengthened by work hardening and aging, giving hardnesses of up to 55-60 Rockwell C and strength levels as high as 260-300KSI.
Due, to this unique combination of properties, MP35N® has many applications in such industries as oil and gas, aerospace and medical. MP35N can be effectively used at cryogenic temperatures without embrittlement and maintain its properties at temperatures up to 600°F, and is also suitable for medical implants and orthodontic/prosthetic devices.
MP35N® is able to resist corrosion to most mineral acid, hydrogen sulfide and seawater environments whilst exhibiting excellent resistance to stress corrosion cracking and hydrogen embrittlement, even at high strength levels. NACE MR0175 allows a hardness of up to 51 HRC for material that has been work strengthened and aged by one of the processes listed in the table below.
Aircraft Materials supplies MP35N® in round bar certified to either AMS 5844 (0.270" - 1.520" diameter) or NACE MR0175 (0.5" - 2.5" diameter), as well as sheet, strip and plate products suitable for medical applications.
