Feb 02, 2006 · Cold rolling is a flat rolled process (sheet steel). The drawing process produces higher mechanical properties and closer size tolerances. The bar hot rolled scale is removed prior to drawing. If the bar is then stress relieved there is little residual stresses to warp the part during machining.
A36 Steel Flat Bar - Hot RolledA36 Steel Flat Bar - Hot Rolled is a common low carbon steel with good weldability, machinability, and corrosion resistance. It has a rougher surface than Cold Rolled Steel. It can be heat treated for surface hardening, and galvanized to resist corrosion.

The material is first hot rolled near to the finishing size and then cold rolled to the required size with highly finished rollers. The hot rolled articles are first immersed in a weak solution of sulphuric acid to remove the scale and washed in water, and then dried. This process of cleaning the hot rolled product is known as pickling.
