Superalloy MP35N (UNS R30035)details(HY industry- Technical Center internal data)

 

MP35N (UNS R30035)

UNS R30035 is a high-temperature alloy for use of fasteners developed by SPS Technologies (precision casting company), a famous us manufacturer of space shuttle fasteners.The alloy is magnetic cobalt nickel chromium molybdenum alloy, has a unique combination of performance, including 300 ksi (2068 mpa) strength, good ductility and toughness, and excellent corrosion resistance, high temperature resistant capacity up to 400 ℃, the whole and titanium alloys are similar.The following HY introduces the mechanism, chemical composition, characteristics, performance and application of MP35N alloy.

 

MP35N(UNS R30035) alloy mechanism

  • The performance of UNS R30035 was achieved by processing hardening, martensitic transformation and aging treatment.Through the cold processing, a part of the matrix produces a solid phase transition from the center cube (FCC) crystal structure to the HCP structure.This shift occurs because of the high content of cobalt in the alloy and is known as a “multiphase reaction.”The presence of two different crystal structures blocks the movement of dislocations and leads to marked intensification.Subsequent aging hardening stabilizes these two stages through the solute distribution process, helping to strengthen them further.
