Hot rolled vs cold formed
WebJul 16, 2024 · In hot-rolled sections and welded sections, the residual stresses are principally due to uneven cooling. For example: in a hot-rolled wide flange beam, the flanges, being thicker than the web, cool more slowly. But the flange tips also cool more quickly than the flange where it joins to the web because the tips have more surface … WebDifference between hot-rolled and cold-formed: 1, cold formed steel to allow cross-section a local buckling, which can make full use of the rod buckling bearing capacity;-section hot rolled steel does not allow local buckling occurs. 2, the residual stress of the hot-rolled steel and cold-formed steel produced by different reasons, so the ...
