Some common types of internal defects in steel wire rod include inclusions, segregations, cracks, and voids. Inclusions are foreign substances that are trapped within the steel during the manufacturing process. Segregations occur when the composition of the steel is not uniform, resulting in areas with different properties. Cracks can occur due to excessive stress or improper cooling during production. Voids are empty spaces or cavities within the steel. These defects can weaken the wire rod and affect its overall quality and performance.
