All ScrewsUltra-strength combined with extreme temperature capabilities

As aerospace engineering advances, so must the materials to meet the technological requirements of this industry. Screws made from MP159 have been developed to provide a solution to high temperature, high strength components. MP159 screws offer strength capabilities similar to other Cobalt Alloys (MP35N) but can be used at much higher temperatures - up to 1100°F, compared to MP35N’s usable limit of 800F. In addition, MP159 screws can be used beyond 1100°F in short term situations.

Key Benefits

  • High ultimate tensile strength of 275 ksi and yield strength of 265 ksi (Cold Worked and Age Hardened) combined with excellent ductility and toughness
  • Similar corrosion resistance compared to MP35N which is usable in mineral acids, hydrogen sulfide, seawater and salt spray environments.
  • Excellent fatigue resistance and creep strength at elevated temperatures
  • Excellent resistance to crevice corrosion, stress corrosion cracking and hydrogen embrittlement

Applications

  • The aerospace industry relies on MP159 screws for its most advanced gas turbine and jet engines, rocket boosters and jet propulsion systems.
  • Power generation and chemical processing utilize MP159 screws for applications that demand high strength at extreme temperatures.
