Carbon Steel Round Bar
1. A179 is a steel grade produced according to American ASTM standards, belonging to the American standard.
2. A53 Carbon steel round bar is applicable to cold drawn high-quality low-carbon seamless steel pipes for heat exchangers and condensers.
3. Round steel has relatively high strength, high hardenability, and very good toughness.
4. The pressure bearing capacity of round steel is guaranteed.
5. Even at high temperatures, round steel has high creep strength and guaranteed durability.
A179 is a steel grade produced according to American ASTM standards, which belongs to American standard. A179 Carbon steel round bar is applicable to cold drawn high-quality low-carbon seamless steel pipe for heat exchanger and condenser.
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.
