NIMONIC PK33 is a nickel chromium cobalt alloy developed for demanding welded sheet components. Molybdenum strengthens the matrix, while aluminum and titanium enable age hardening. It combines elevated-temperature strength with useful ductility after welding and resistance to thermal cycling. Turbine combustion hardware is a principal application, and solution treatment followed by aging establishes the final operating condition.
