astm a370 charpy impact test temperature

Semi automatic impact testing machines for jb-300b mainly used for determination of metal materials under dynamic load, impact resistant performance, so as to judge the material under dynamic load resistance to impact the performance. The impact test flight semi automatic control testing machine simple artificial, high work efficiency, Yang put, put are automatic control and is in particular applicable to continuous do impact test in the laboratory and do a lot of impact test of metallurgy, machinery manufacturing, iron and steel industry.

Jb-300b swing hammer impact testing machine is my company strictly in accordance with the GB/T3038-2007< swing hammer impact testing machine > and GB/T229-1994< metallic materials Charpy Notch Impact test method > developed another new product. The biggest impact energy 300j and 500J with 150j and 250J pendulum each one. The sample section for 10mmX10mm. mainly on the impact toughness of the large black metal, particularly is iron, steel and alloy.
