SAE 1018 Cold Drawn Steel Square Bar
AISI 1018 mild/low carbon steel has excellent weldability, produces a uniform and harder case and it is considered the best steel for carburized parts. AISI 1018 mild/low carbon steel offers a good balance of toughness, strength and ductility. AISI 1018 hot rolled steel has significant mechanical properties, improved machining characteristics and has a high Brinell hardness measure.
Cold rolled 1018 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 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.
