YYF-20 slow strain rate stress corrosion testing machine manufacturer
Equipment Description:
This testing machine is a new type of microcomputer controlled slow strain rate stress corrosion testing machine jointly developed by Shanghai Bairuo Testing Instrument Co., Ltd. and Shanghai Jiao Tong University. It uses high-precision sensors for force measurement, high-speed and ultra high resolution data acquisition cards for data acquisition, and computer load, time, deformation, displacement and other numerical and graphical display and processing. It can perform various control methods such as load, deformation, displacement, etc.
Select products for key components of the equipment to ensure stable and reliable operation of the system.TestLiveThe experimental software has a fully Chinese interface and powerful data processing functions. The experimental conditions and results are automatically saved, and the experimental data, curves, and reports are displayed and printed. This machine is an ideal cost-effective experimental equipment for research institutes and colleges.
Slow strain rate（SSRT）Stress corrosion（SCC）The testing machine is mainly used to simulate the tensile, compressive, bending, creep and other tests of metal, non-metal, composite materials and their finished products under different working conditions such as temperature, pressure and environmental media, according to the requirements of use, to test the stress corrosion resistance of materials under slow rate conditions.
