(1) d is the diameter of the bending center and a is the thickness of the sample.
(2) The impact test is calculated according to the average value of three samples in a group. The single value of one sample of SM490B steel plate is allowed to be lower than the specified value, but not lower than 70% of the specified value.
Note: Trace alloying elements can be added if necessary
a.
