Haynes 25 / L605

Haynes 25 (L605 / UNS R30605), excellent strength, good oxidation resistance, 1800°F (980°C) resistance, very good vulcanization resistance, and relatively good wear resistance and abrasion resistance. Used in gas turbine parts, bearings and various industrial applications.


Haynes 25 alloy is a cobalt-nickel-chromium-tungsten alloy that has excellent high-temperature strength and an oxidizing environment up to 1800°F (980°C), can be exposed for a long time, and has excellent resistance to sulfuration. It can be manufactured and shaped by conventional techniques and has been used for casting parts. Other attractive features include excellent resistance to metal abrasion.

Genenal Introduction
Alloy L605 is a non-magnetic, solid solution, Co-Ni-Cr-W superalloy that is useful for continuous service to 1800°F (980°C). Its good strength can be upto 2150°F. AMS 5759 requires minimum yield strength of 45,000 psi at room temperature. L605 maintains good oxidation resistance up to 1900° F. L605 has a unique ability to resist corrosion in very severe environments. Highly resistant to hydrochloric acid, nitric acid and wet chlorine (subject to need for exercising care in its selection at certain con¬centrations and temperatures)

L605 is the strongest of the fabricable cobalt alloys and has been the subject of many investigations to determine its properties over a wide of conditions because of its long and widespread use. Alloy L605 exhibits a loss of room temperature ductility in much the same way as other superalloys, such as alloy X or alloy 625, when exposed for prolonged temperatures at intermediate temperatures.
