Note : Transversal specimen is adopted in the tensile test, thus the long axis of specimen is vertical to rolling direction.
ongitudinal specimen is used in impact test, and the impact value is obtained from standard specimen (10 × 10 × 50mm); The impact value shall be reduced with equal proportion if the smaller sized specimen is used, such as 5mm,7.5mm.
Transversal specimen is used in the bending test. d=bending diameter，a=plate thickness
