Drop Tower – Drop Weight Tester for Nil-Ductility Temperature (NDT) of Ferritic Steel
Drop Tower – Drop Weight Tester for Nil-Ductility Temperature (NDT) of Ferritic Steel ToronNDT™ 3000
ToronNDT™-3000 Drop Weight Tester is a high-energy Drop Weight Tester designed to determine the Nil-Ductility Temperature (NDT) of ferritic steels in accordance with recognized international test methods.
Nil-Ductility Temperature represents the highest temperature at which a ferritic steel specimen fails by brittle fracture under dynamic impact loading. This parameter is critical for evaluating fracture resistance and low-temperature performance of structural steels.
The ToronNDT™-3000 operates by raising a hammer of specified mass to a controlled height and releasing it from a static condition, allowing free-fall impact onto a standardized specimen. The system automatically determines whether fracture occurs and supports repeat testing to identify the transition temperature accurately.
With fully automated hammer lifting, specimen feeding, impact execution, and sample recovery, the ToronNDT™-3000 delivers consistent, repeatable NDT results while improving operator safety and testing efficiency.
