DWT-2000 astm drop weight impact test

Application & Features:

The machine 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.

It confirms to Standards: ASTM E208 -‘Standard Test Method for Conducting Drop-Weight Test to Determine Nil-Ductility Transition Temperature of Ferritic Steels’.
