SAE1045 C45 Carbon Steel Round Bar

Carbon steel bar is a kind of solid long steel, and the common ones are round steel, square steel, hexagonal steel, octagonal steel, etc. Round steel is often used to make steel bars, bolts and various mechanical parts, as well as billets for seamless steel pipes. Square steel refers to steel that is rolled or processed into a square section, which can be divided into hot-rolled and cold-rolled.

Product Description

Carbon steel bar is a kind of solid long steel, and the common ones are round steel, square steel, hexagonal steel, octagonal steel, etc. Round steel is often used to make steel bars, bolts and various mechanical parts, as well as billets for seamless steel pipes. Square steel refers to steel that is rolled or processed into a square section, which can be divided into hot-rolled and cold-rolled. 


What is carbon steel round bar?

Carbon steel round bar is a solid long steel bar with a circular cross-section. Its specifications are expressed in diameter in millimeters (mm). The calculation formula of theoretical weight of round steel: outer diameter Х outer diameter Х0.00617=kg/m. Round bars are divided into three types: hot rolled round bars, forged round bars and cold drawn round bars according to the process section. According to the chemical composition (ie carbon content), it can be divided into low carbon steel round steel, medium carbon steel round steel and high carbon steel round steel. According to the quality of steel, it can be divided into ordinary carbon steel round steel and high-quality carbon steel round steel. According to the use, it can be divided into carbon structural steel and carbon tool steel.

Types of steel and their grades:

Ordinary carbon structural steel 

Q195, Q215, Q235Good plasticity, can be rolled into steel plates, steel bars, steel pipes, etc.
Q225, Q275Can be rolled into shaped steel, steel plate, etc.
High quality carbon structural steel20#, 45#, etc.Mainly used to manufacture various machine parts
Carbon Tool SteelT9, T12 etc.Mainly used to manufacture various props, measuring tools, molds, etc.
cast steelZG25 etc.

It is mainly used to manufacture parts with complex shapes and require certain strength, plasticity and toughness,

 such as gears, couplings, etc.
