SA573 grade 70 carbon steel plate sheet surface cracks refer to the linear cracks on the surface of SA573 grade 70 carbon steel plate sheet, which should generally be the same as the forging or rolling direction. Formation reason: it is mainly due to the hairline, hot crack and cold crack caused by surface over burning, decarburization, looseness, deformation and excessive internal stress during processing (forging, rolling, heat treatment, quenching and tempering), as well as the high content of sulfur and phosphorus impurities on the surface. Inspection method: SA573 grade 70 carbon steel plate sheet surface cracks can be detected by naked eye observation, acid pickling, magnetic particle inspection, coloring inspection and metallographic method.
