And baking temperature stress 180° C for 30 minutes to make a micro-Vickers hardness test using solid phase absorbed deep skin 550.HMV and check the structure as a comma.
Stress and bake at 180 ° C for 30 minutes, the micro Vickers hardness testing using the term deep 550.HMV rigid criteria and determine the microstructure.
Baking temperature and stress 180 ° C time 30 minutes. The micro Vickers hardness test โดยใช้ระยะ costume solid surface 550.HMV criterion and check the microstructure.
