MP159 Forgings
R30159
Strengthening of super alloys is performed by work hardening, solid-solution hardening, and precipitation hardening methods. MP159™ is a multiphase cobalt-nickel-chromium alloy with ductility, corrosion resistance, and ultra-high strength.
Super alloys contain many elements in a variety of combinations to obtain desired results. These alloys are good for use at high temperatures and severe mechanical stress, and also in cases where high surface stability is needed. Super alloys provide good creep and oxidation resistance.
