Slow Strain Rate (SSRT) Stress Corrosion Cracking (SCC) Testing Machine

Slow stress corrosion tensile testing machine

Product Model:MYFT-50

Product UsageSlow strain rate（SSRT (Stress Corrosion Cracking) Testing MachineUsed for conducting corrosion slow tensile tests on materials in corrosive environments. The optional experimental kettle provides testing conditions in a medium environment, achieving a testing environment from room temperature to high temperature, and from atmospheric pressure to high pressure.

Configuring the DCPD crack propagation measurement system and replacing it with a loading unit for fatigue testing can achieve corrosion fatigue loading and continuous measurement of crack propagation length and crack propagation rate in corrosive environments. The standard configuration is a slow loading system, which calculates the material change characteristics for 1000 hours and longer through 100 hour experiments.
