HST-HFT-A SERIES 2-Column Hydraulic Servo Fatigue Testing Machine
Product description:
HST-HFT-A SERIES 2-Column Hydraulic Servo Fatigue Testing MachineIt is mainly used to detect the static and dynamic mechanical properties of metal and nonmetal materials. It can realize mechanical tests such as tension, compression, tension-tension, compression-compression and tension-compression, as well as high-cycle fatigue, lowcycle fatigue, crack growth, fracture toughness and other tests, and realize various waveform outputs such as sine wave, triangle wave, square wave, etc.
