Carbon Steel: Properties, Production, Examples and Applications
Carbon steel is an iron-carbon alloy, which contains up to 2.1 wt.% carbon. For carbon steels, there is no minimum specified content of other alloying elements, however, they often contain manganese. The maximum manganese, silicon and copper content should be less than 1.65 wt.%, 0.6 wt.% and 0.6 wt.%, respectively.
Types of carbon steel and their properties
Carbon steel can be classified into three categories according to its carbon content: low-carbon steel (or mild-carbon steel), medium-carbon steel and high-carbon steel . Their carbon content, microstructure and properties compare as follows:
Carbon content (wt.%) | Microstructure | Properties | Examples |
Low-carbon steel | < 0.25 | Ferrite, pearlite | Low hardness and cost. High ductility, toughness, machinability and weldability |
Medium-carbon steel | 0.25 – 0.60 | Martensite | Low hardenability, medium strength, ductility and toughness |
High-carbon steel | 0.60 – 1.25 | Pearlite | High hardness, strength, low ductility |

PRODUCT DETAILS
A105 Round Steel Bar Description |
A105 steel bars are widely used in high temperature, high pressure and corrosive environments. This is because A105 has excellent mechanical properties and corrosion resistance. It has high strength and strength, can withstand high pressure and high temperature, and has good performance. In addition, A105 also has good processability and welding performance, making it easy to manufacture and repair. A105 can be used in chemical, petroleum, food and other industries. During the manufacturing process, A105 typically requires forging and heat treatment. Forging can change the internal structure of a metal and improve its mechanical properties. Heat treatment can change the surface structure and hardness of the metal, further improving its mechanical properties and corrosion resistance. |
