Abstract
The steel plate material property testing device determining a material property of a surface of the steel plate by generating the eddy current in the steel plate includes: an eddy current tester disposed so as to face the steel plate; and a frame to which the eddy current tester is fixed, in which the eddy current tester includes: a coil disposed so as to form an alternating-current (AC) magnetic field in only one direction; an AC power supply unit connected to the coil; a sensor unit connected to the coil; and a material property determination unit connected to the sensor unit and determining the material property of the steel plate based on a measured signal obtained through the sensor unit.
