Ultra-strength combined with extreme temperature capabilities

• Extreme high strength properties up to 275 ksi ultimate tensile.
• Maintains superior strength to 1100°F.
• MP159 chemisty and specification
• Datasheet for MP159

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