Facilities
Fatigue Testing Machines (2 sets)
FEATURES
  • Here are 2 sets of fatigue testing machines operated by servohydric power force, installed by INSTRON company of U.S.A.
  • Loading capacity is 25ton maximum. Lording cycle is 20Hz maximum.
  • Testing temperature is 1600℃ in open air condition and 2000℃ in vacuum or inert gas environment.
  • Heating methods are by means of induction and various kinds of resister such as tungsten heater and so on.
