Udimet Alloy L-605 / Haynes Alloy 25 is a solid solution strengthened cobalt-chromium-tungsten nickel alloy which combines excellent high temperature strength and oxidation resistance to 2000°F with good resistance to sulfidation, wear and galling. Alloy L-605 / Alloy 25 has good forming characteristics and is capable of being forged, hot worked or cold worked, althoug it does work-harden very rapidly so frequent intermediate annealing treatments are recommend for complex forming operations. Alloy 25 / L-605 can also be readily welded by most conventional welding methods using similar composition welding wire (AMS 5796) or coated electrodes (AMS 5797). Alloy L-605 / Alloy 25 is supplied solution heat treated in the range of 2150-2250°F and rapid air or water quenched to attain optimum properties. Alloy L-605 / Alloy 25 has many applications in military and commercial gas turbine engine components such as rings, blades and combustion chamber parts although for many modern engines it has largely been replaced by Alloy 188 or Alloy 230.
