High Temp Inserts for Specimens with Gauge Length Ridges

W-C016-J3 | High Temp Inserts for Specimens with Gauge Length Ridges

High Temperature Notched Replaceable Inserts are made from the 214 alloy, which offers superior high temperature performance. The notched inserts are machined with a 90 degree notch for use on creep specimens with machined ridges at each end, which establishes the gauge length of the specimen.

Replaceable knife edges allows the extensometer gripping knife edges to be replaced when they get dull or changed to accept a different specimen type or size. Older style extensometers required the knife-edges to be machined or heads completely replaced. With extensometers that accept these inserts, only the inserts have to be replaced, this means great cost savings.

Features Include:

• High temperature, high corrosion resistant 214 alloy is used. Lifetimes can exceed 4700 hours at 1100 Deg. C (2000 Deg. F) depending on the knife-edge wear.
• Inserts are available for either flat or round specimens: Rounds: 6.4 to 12.8 mm (0.252 to 0.505 in) diameter Flats:6.35 to 12.7 mm (0.250 to 0.5 in) thick and 16 mm (0.625 in) wide are available.
• Precision machining is done based on the specific specimen size being tested for excellent concentricity, which minimizes specimen bending. SPECIFY SPECIMEN SIZE AT TIME OF ORDERING
• The price includes one set (4) of inserts. Two split halves for the top and two split halves for the bottom, (enough to replace one extensometer).
