Usually, when the composition segregation, the presence of gases and inclusions, and the forging temperature forging ratio are misunderstood, the problem occurs more often. Since the raw material of u-shaped steel often has band segregation, component segregation remains after hot pressing, and this segregation can be seen from the annealed structure after quenching. Moreover, it is precisely because of segregation that the u-shaped steel is heated closed to the solidus line in an oxidizing atmosphere, and it is easy to produce precipiates or impurities, which is the main cause of defects.
