The geometrical tolerances are usually smaller for cold-formed sections. The material properties and also be different. For example the final grain structure of the metal will be different, and cold-formed sections usually have higher residual stresses than hot-formed.

Comparative experimental study of hot-formed, hot-finished ...

The tested hot-formed and hot-finished hollow sections were of dimensions 180 mm × 180 mm × 12.5 mm, while the cold-formed hollow section was of dimensions 200 mm × 200 mm × 12.5 mm. Surface discontinuities including rolled-in scale and pitting, indentations and roll marks, scratches and grooves, spills and silvers, blisters, sand patches, cracks, shell, and seams were examined.

2, the residual stress of the hot-rolled steel and cold-formed steel produced by different reasons, so the distribution of the cross section is also very different. The residual stress distribution in the cross section of cold-formed steel bending, residual stress distribution in the hot rolling steel or welded steel cross-section is a film type.
