Instrumented Charpy impact testing of V-notched cut from rolled plates in different positions and directions was made at temperatures -196° to 200°C. Absorbed energy E
a and crack propagation energy E
p depend on the cutting-off position and direction and on the testing temperature to a great degree. The specimen cut in the direction parallel to the rolling direction in which a standard V-notch lies on the rolled surface has the highest E
a and E
p. The specimen cut in the direction transverse to the rolling direction in which a V-notch lies in the direction transverse to the rolled surface has the least E
a and E
p. The highest E
a and E
p are 1.5 times or more of the least ones. The minimum temperature dependence is found in the specimen having the maximum E
a. A linear relation lies between E
a and E
i + E
p, where E
i is crack initiation energy. E
i + E
p is about 0.75 to 0.78 times of E
a.
