    Characteristic as below:

    HY Co25(UNS R30605/Stellite 25 )is resistant to oxidation and carburization up to 1900°F. The alloy resists wet chlorine at ambient temperatures and is resistant to nitric and hydrochloric acids under certain conditions. Exposure testing is recommended to verify performance.

    Processing conditions and application:

    Metal working tools where a combination of metal-on-metal wear, thermal fatigue and hot corrosion resistanceare required, such as piercing points, forming tools, and extrusion dies. Also used for furnace hardware.
