JL-3000 No Plastic Transition Temperature Drop Hammer Impact Test Machine

 

This machine is used for no plastic transition temperature test for ferrite steel. NDT temperature is the highest temperature while standard sample breaking according to ASTM E208-2006、GB/T 6803-1986 standard.It shows the highest temperature of the cracked steel under dynamic load yield stress.


 


This machine is composed of host frame, lifting, hammer, anvil bed, safety protection and control system.The impact energy is adjusted through adjustment of weight Thallium quantity and impact height.It has the function of preventing the secondary impact and automatic feeding.Accurate and fast sample centering, energy range stepless adjustable, energy automatic display. Touch screen display, highly automatic.
