A Full Complement of High-Temperature GripsSelecting the right grips for high-temperature materials testing involves a careful consideration of maximum test temperature, heating method and specimen geometry. MTS provides a full complement of precision, high-quality grips to meet your specific high-temperature materials testing requirements.
For temperatures up to 1000°C (1800°F), Model 680 Grips offer nickel-based superalloy construction and can be enclosed in a furnace. Water cooling occurs away from the point of contact to ensure uniform gradients near the specimen, which can be buttonhead or threaded.
For temperatures up to 540°C (1000°F), Model 647 All-Temperature Side-loading Hydraulic Wedge Grips can operate within an environmental chamber. The wedges (flat or vee) open and close remotely, so changeover of flat or round specimens with smooth shanks can be performed quickly.
Model 647 Side-loading Hydraulic Wedge Grips are also available with water-cooled wedges for testing at temperatures up to 175°C (347°F). These wedges (flat, vee or round) can be used for a much wider variety of both high-temperature and conventional testing of flat or round specimens, providing a more cost-effective overall solution.
Model 646 Hydraulic Collet Grips are “cold” grips designed for testing round specimens at temperatures up to 65°C (150°F). The entire grip body is water-cooled, so they are ideal for applications that use induction heating. Plus, these grips offer superior alignment for brittle specimens.
