MP35N nickel bar manufacture, MP35N nickel wire rod Alloy MP35N® (AMS 5844/AMS 5845/ NACE MR0175)

Short Description:

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.
