application
This machine is an important instrument and equipment for testing the physical properties, mechanical properties, process properties, structural properties, and internal and external defects of steel strands, threaded steel and their products. It can automatically obtain performance indicators such as tensile strength, yield strength, specified non proportional elongation strength, elastic modulus, etc. of the measured material, and can complete closed-loop control such as constant rate loading, constant rate deformation, constant rate displacement, and constant rate strain.
