Carpenter Pyromet® CTX-3 Superalloy, Heat Treated
Categories:	Metal; Superalloy; Iron Base
Material Notes:	Data provided by Carpenter Technology Corporation. Pyromet® alloy CTX-3 is a high strength, precipitation hardenable superalloy which exhibits a low CTE over a broad temperature range. This alloy also possess high hot hardness and good thermal fatigue resistance. It is weldable, brazable, and can be chromium plated. This material offers significant improvement in notched stress-rupture strength over Pyromet alloy CTX-1. Retained hot-cold work is not required for good stress rupture properties and is not affected by stress orientation. Pyromet® is a registered trademark of Carpenter Technology Corporation.
