3 & 4 POINT
BEND FIXTURES
OVERVIEW
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 for corrosion resistance superior to stainless steels.
