ZCJ2000 Drop Weight Impact Testing Machine


Big Picture
Model:ZCJ2303

Model: ZCJ2303, ZCJ2304
 
Max impact energy: 3000J, 30000J
 
Features:
   
    The ZCJ2000 series Drop Weight Impact Testing Machine is suitable for performing DWTT or NDT test. The test method is to raise the striker to a specific height then release, free drop striker impacts the specimen and realize dynamic loading. It consists of the model ZCJ2303 and the model ZCJ2304.
 
    The model ZCJ2303 is specially designed to determine Nil-Ductility transition (NDT) temperature of ferritic steels. NDT temperature is the highest temperature at which the specimen fractures. It means the highest temperature at which the steel material with small cracks fractures under dynamic yield stress. This test method is that raise the striker to a specific height then release, free drop striker impacts the specimen and realize dynamic loading. After impact, evaluate the specimen and adjust cooling temperature, conduct many times test to get NDT temperature.
 
Conform to ASTM E208 <Standard Test Method of Conducting Drop-weight Test to Determine Nil-Ductility Transition Temperature of Ferric Steels>
 
    ZCJ2304 is mainly used for drop weight tear test (DWTT) of Ferritic Steels, to observe specimen fracture surface after impact within the temperature that fracture type is converted from non-ductility to ductility. This test method is that striker with some weights is raised to some height then released. Free drop striker impacts and tears the specimen. After impact, observe shape and features of fracture surface.
Special features:
   
Conform to ASTM E604 <Standard Test Method For Dynamic Tear Testing of Metallic Materials>
