Technical Information — CTS™-XHP
CTS™-XHP is a powder metallurgy, high-carbon, high chromium stainless steel with very good stainless properties at high hardness. It can be heat treated to 64HRc and its fine carbide distribution and fine grained microstructure greatly enhance cutting performance in knife blade applications.

Preheat: 1400/1450°F, equalize.
High Heat (Austenitizing): 1850-2000°F, hold 20-45 minutes at temperature. Quench: Air, positive pressure vacuum, interrupted oil. Cool to 150°F. After quenching the alloy can be refrigerated at nominally -100°F for one hour and warmed to room temperature to minimize retained austenite.
Temper: 250-800°F, hold two hours at temperature. Tempering between 800 and 1100°F should be avoided due to a decrease in both toughness and corrosion resistance.
|Tempering Temperature °F||HRC|
Heat to 1550/1600°F, hold two hours, slow cool 25°F/hour to 1200°F, then air or furnace cool to room temperature.
Heat to 1600°F, hold two hours, cool to 1300°F, hold four hours, then air cool.
Annealed Material: Heat to 1200/1250°F, hold two hours, cool in still air
Hardened Material: Heat to 25°F below tempering temperature, hold two hours, cool in still air.
