A53 is a steel grade produced according to American ASTM standards, which belongs to American standard. A53 Carbon steel round bar manufacturing requires parts with low stress and high toughness, such as car body, container, deep stamping vessels, pipes, gaskets, etc., which can be used for cold rolling, cold punching, cold heading, cold bending, hot rolling and other processes, as well as carburizing parts with low central strength, carbonitriding parts, etc.

Now the common round steel processes are hot rolling, forging and cold drawing. The steel quality and application scope of these three processing modes will also have some differences. For example, the specification of hot rolling is generally 5.5-250MM, and the appropriate steel can be selected according to the actual needs.
Generally, parts are manufactured by machinery or used as seamless steel pipe blanks, and steel is also used in some building construction.
Round steel has relatively high strength, high hardenability and very good toughness, so its pressure bearing capacity is also guaranteed. Even if it is used at high temperature, the creep strength is high and the durability is also guaranteed.

Round steel belongs to carbon structural steel for construction and machinery, while square steel belongs to carbon structural
steel for machinery. Both of them are simple section steel, and their section shapes are respectively round and square. Low carbon is mainly used for
drawing wire, forging rivets, bolts, nuts and other metal products of raw materials. Medium carbon round steel and square steel
are generally used to make mechanical structural parts.
