Model 680 High-Temperature LCF Grips

Model 680 High-Temperature Grips were expressly designed for high-temperature, low-cycle fatigue testing, but can also be used for other types of tension-compression or tension-only testing. The grip heads and extension rods are constructed of high-temperature, super alloys selected to extend into the heated zone of the furnace, minimizing the thermal gradients within the specimen.

TECHNICAL OVERVIEW

Model 680 High-Temperature Grips were expressly designed for high-temperature, low-cycle fatigue testing, but can also be used for other types of tension-compression or tension-only testing. The grip heads and extension rods are constructed of high-temperature, super alloys selected to extend into the heated zone of the furnace, minimizing the thermal gradients within the specimen. Accessories for these grips include a hand pump (required), your choice of buttonhead or threaded specimen adapters, and a water cooling kit.
