Cold rolled steel is essentially hot rolled steel that has had further processing. The steel is processed further, where the material is cooled (to room temperature) followed by annealing. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes. Is descaled steel better than hot rolled steel?Is descaled steel better than hot rolled steel?Descaled steel also offers a better surface for painting and other surface coatings. Cold worked steels are typically harder and stronger than standard hot rolled steels. Cold rolled steel is essentially hot rolled steel that has been through further processing.Hot Rolled vs Cold Rolled Steel Metal Casting Blog

Sep 11, 2014Uses Hot rolled products like hot rolled steel bars are used in the welding and construction trades to make railroad tracks and I-beams, for example. Hot rolled steel is used in situations where precise shapes and tolerances are not required. Cold Rolled Steel. Cold rolled steel is essentially hot rolled steel that has had further processing.Electric Resistance Welded Tubing Industrial Tube and hot rolled d c type steelCold rolled electric welded (CREW) tube is produced per ASTM A513 Type 2. CREW is produced from hot rolled strip steel that has been cold reduced. Due to the extra cold working at the steel mills, A513 Type 2 tubing will have tighter wall thickness tolerances, improved surface condition and a narrower range of mechanical properties than A513 Type 1.Formation mechanism of surface scale defects in hot hot rolled d c type steelJan 01, 2014The oxide scale shows various behaviors in hot rolling; (a) uniform deformation with matrix steel, (b) cracking, (c) fragmentation, (d) indentation to matrix steel, etc. Through observations using glass coating, it is found that the behavior strongly depends on the rolling temperature as well as the scale thickness before rolling.
