SAE1045 C45 Carbon Steel Round Bar ASTM

According to the process, round steel is divided into three types: hot-rolled round steel, forged round steel and cold-drawn round steel. According to chemical composition (that is, 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 bar and high-quality carbon steel round bar. According to the application, it can be divided into carbon structural steel and carbon tool steel.

1.The most competitive price
2. ISO certified excellent manufacturer
3. Third party inspection: SGS, CE, etc.
4. Sufficient inventory, Fast delivery

PRODUCT CATEGORY

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.
