Our company was commissioned by a steel mill in China, using non-destructive hysteresis assessment technology to evaluate the internal stress of a batch of steel plates.

Steel plate material: pipeline steel L485, specification: 20×2470×12150mm

        Hysteresis nondestructive assessment technology can be measured directly on the workpiece surface without grinding the surface, no coupling, up to 6mm lifted, data acquisition only 3 seconds, data can be stored in real time, built-in software can map the coercivity color distribution, red areas represent danger areas (i.e., high stress areas).
