Uneven pressure distribution between rolls causes these marks, affecting dimensional accuracy and surface quality. 5. Laminations: Thin layers or bands of non-metallic inclusions parallel to the steel's surface, caused by inadequate refining or improper casting techniques, are known as laminations. They reduce strength and toughness, requiring further processing or rejection. 6. Decarburization: The loss of carbon content on the steel's surface, occurring during heating, annealing, or hot working, is referred to as decarburization. It decreases hardness and strength, potentially leading to premature failure. 7. Surface cracks: Visible cracks on the steel's surface, caused by excessive cooling rates, improper heat treatment, or mechanical stress, are surface cracks. They compromise structural integrity and may necessitate repairs or rejection. These examples cover just a few of the possible surface defects in steel round bars. It is crucial to inspect and address these defects to ensure the steel's quality and performance in various applications.
