In general, the cause of slab cracking during heat treatment has been analyzed with focus on processing conditions. However, in the present work, the cause of cracking is analyzed based on the microstructural evolution during heat treatment. The microstructural analysis indicates that the structure of the slab consists of three main regions as the top, quarter, and center parts. The tensile properties are investigated in each region of the slab in the temperature range from 25 to 350 °C. Results demonstrate that the cracking is mainly attributed to the thermal stress and specific morphology of the microstructure. It is proposed that the cracking during the heat treatment is related to the presence of inclusion at the ferrite phase which is located at the boundary of pearlite grains.
