NDT-3000 Digital Display Nil Ductility Transition Temperature Drop Impact Test Steel Ball
NDT Nil Ductility Transition Temperature impact test steel ball
Application:
This impact test steel ball is applicable for nil ductility transition temperature testing of ferrite steel. NDT temperature is the highest temperature when the standard specimen is broke according to the standard of ASTM E208-2006,GB/T 6803-1986. Also means the highest temperature of the crack steel occurred brittle fracture under dynamic loading yield stress .
Standard: impact test steel ball
ASTM E208-2006,GB/T 6803-1986
Features: impact test steel ball
Composed by framework, ascension, hammer body, the anvil block, safety protection and control systems.
Through adjusting the number of weight thallium and impact height to adjust the impact energy.
With anti secondary attack, automatic send sample function.
Specimen alignment is accurate and fast, energy range stepless adjustable, with energy automatic display function
