S235JR SS400 Cold Drawn Steel Flat Rectangle Bar
Cold finished bars are produced from special bar quality hot rolled bars by cold drawing, turning, grinding, polishing, or by a combination of these methods.
Cold drawing increases a bar's yield strength and tensile strength, turning improves surface quality, grinding produces more precise tolerance ranges, and polishing further creates a smooth and attractive surface. Overall, cold finishing reduces the cross sectional area of the hot rolled bar. CF steel bars may be harder to work with than their hot rolled equivalents, but they make up for it with more accurate sizes, smooth surfaces, increased mechanical properties and machinability.

s20c cold drawn hexagonal steel bar Cold rolled s20c hex steel bar is a low carbon steel grade with good weldability and formability for a various applications. 1018 cold drawn steel bar are usually used in many industries like automotive, agriculture, construction and motorcycle. Cold finished steel is cold drawn or cold rolled by hot rolled steel. It is typically produced as turned bars or cold drawn bars. Cold drawn steel bar is accomplished by cold drawing a bar through a mould.
