Slow strain rate stress corrosion testing machine

 Function summary

       Slow strain rate stress corrosion testing machine is mainly used to test metal samples and non-metallic materials (including bars and plates) in NaOH, NO3-, H2S, CL- solution, methanol, N2O4, NH3, wet air and water and other media environment,And in the set temperature (temperature range: normal temperature -60°C) environment,Test for the determination of stress corrosion failure characteristics of metals。It has force, time, loading rate, step (multistage) loading and other control modes, and the conversion between various modes has no impact。
