3&4 Point Bend Fixtures

Bend fixtures are typically used for applying constant stress to a sample for an extended period of time. The stress is applied by deflecting thin metal samples a specified amount using a loading apparatus. While this deflection is maintained, the fixtures are placed in a corrosive environment within a hydrogen induced cracking (HIC) tank or autoclave for the duration of a test. These bend fixtures are the same as specified in ASTM G39 and NACE TM0177 – Method B. A loading fixture can be included to simplify the deflection measurement. All Cortest fixtures are made from Hastelloy C-276 material, a superior solution to coated 316 S.S. fixtures.
