Aug 19, 2020 · Cold rolling has higher dimensional accuracy than hot rolling. 3) Difference in process. 1. The cold-rolled formed steel allows local buckling of the section, which can make full use of the bearing capacity of the bar after buckling; while the hot-rolled steel does not Electric Resistance Welded Tubing Industrial Tube and Hot rolled electric welded (HREW) tube is produced per ASTM A513 Type 1A. HREW mechanical tubing is produced from hot rolled strip steel while A513 Type 1B tubing is produced from hot rolled strip steel that has been pickled to remove scale then oiled to provide a cleaner surface than hot rolled. A513 Type 1 tubing provides more specific tolerances for OD, wall thickness, length and straightness tolerances than pipe and structural tubing

In a welded pipe, the seam or the weld-joint is the weaker part of the pipe limiting the strength of the pipe to the strength of the weld-joint. Regardless of whether the stainless steel is hot or cold rolled coil, the welding process is the same. First, the coils are separated into designated widths. Next, forming processes are applied. Steel Suppliers in Southern California Steel Suppliers Hot rolled steel involves rolling the steel at temperatures over 1,700°F to make it easier to shape and form. After forming is complete, the steel is cooled. Hot rolled steel is typically used for construction and other applications that do not require precise shapes and tolerances. Cold rolled steel is heated and cooled just like hot rolled
