What is Carbon Steel Round Bar vs Rod?
Carbon steel is a versatile grade that can be designed as round bars and rods. Both these components are used interchangeably and can be distinguished from certain key features.
- A carbon steel rod is straight in size and can be shaped in circular cross sections. A rod is completely sealed with no openings.
- A carbon steel round bar is designed with a uniform cross-section area that is smaller in size compared to its actual length. A round bar can be characterized by a hollow opening.

AISI 1045 Carbon Steel Round Bar vs Sae 1018 Round Bar
Carbon steel is the commonly used round bar grade. These bars are designed in 1018 and 1045 grades and both can be differentiated based on certain features.
- AISI 1045 carbon steel round bar is designed with a higher carbon content of 0.45% as compared to the Sae 1018 round bar having a carbon content of 0.18%.
- 1018 grade round bars have a tensile strength of 64,000psi with a yield strength of 54,000psi. They can be elongated by minimum of 15%. The 1045 round has a tensile strength of 91,000psi with a yield strength of 77,000psi. They can be elongated by a minimum of 12%.
- The carbon grade of 1045 possesses a hardness of 179 Brinell. Similarly, the 1018 grade exhibits a hardness of 126 Brinell.
- 1018 round bar is generally cost-effective when compared to a 1045 carbon steel round bar.

1144 Carbon Steel Rod vs 12l14 Cold Rolled Round Bar
- The tensile strength of an 1144 carbon steel rod lies between 750mpa up to 840mpa. Similarly, the tensile strength of the 12l14 cold rolled round bar lies between 440mpa up to 620mpa.
- 1144 carbon steel rod is designed with higher Brinell hardness compared to 12l14 cold rolled round bar.
- The 12l14 grade bars showcase a slightly higher melting range than the 1144 carbon steel rod.
