Superior atmospheric corrosion resisting structural steel strips cold bending property is always below the standard or fall short of using request. The reason is found out by using chemical composition analysis, microstrueture examination, mechanical property testing and productive process research. C species inclusion is the main influence factor in cold bending property of the Superior atmospheric corrosion resisting structural steel strips, in the next place, the cold bending property is deeply affected by Chemical composition, microstructure and mechanical property.
