Abstract:There are many cracks in Q195 hot rolled strip during cold bending. By means of chemical, mechanical, metallographic and electron microscope energy spectrum analysis, the components, properties, inclusions, structures and other aspects of the cracked samples and the qualified samples were compared and analyzed. The analysis shows that the high content of inclusions is the main reason for the cold bending cracking of Q195 strip, but the chemical composition and matrix structure also have an important influence on the cold bending properties.
