MP159 chemisty and specification
Datasheet for MP159
As aerospace engineering advances, so must the materials to meet the technological requirements of this industry. Fasteners made from MP159 have been developed to provide a solution to high temperature, high strength components. MP159 fasteners 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, 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 fasteners for its most advanced gas turbine and jet engines, rocket boosters and jet propulsion systems.
Power generation and chemical processing utilize MP159 bolts for applications that demand high strength at extreme temperatures.
