charpy impact test vs temperature

Impact Testing Machine is developed as per GB/T4158-2002 <Inspection of Pendulum impact testing machine> and can finish impact test according to GB/T229-2007 <Method of Metal Charpy Gap Impact Test>. It can realize two kinds of impact energy 300J and 150J. The section area of specimen is 10×10mm. mainly use to test larger impact toughness ferrous metal, such as: steel and alloy material.
Its principle is to calculate difference of the energy before and after pendulum impacting, the difference is energy which absorbed by specimen. The machine can be operated by semiautomatic, easy to operate, and high efficiency. Furthermore, it can swing up the pendulum automatically by using residual energy. It is especially suitable for continuous test.
