Carbon steels have carbon as the key alloying element in their composition. They also contain up to 0.4% silicon and 1.2% manganese. In addition, the residual elements such as copper, molybdenum, aluminium, chromium and nickel are present in these steels. AISI 1035 carbon steel is a water resisting carbon steel whose wear resistance and hardenability are increased by the addition of small quantity of chromium.

Strength: 1035 carbon steel has moderate strength, making it suitable for applications that require moderate mechanical strength. It has a minimum tensile strength of 585 MPa and a minimum yield strength of 360 MPa.
Ductility: 1035 carbon steel has good ductility, which means that it can be easily formed and shaped without cracking or breaking. This property makes it ideal for applications that require complex shapes or designs.
Machinability: 1035 carbon steel has excellent machinability, which means that it can be easily machined using common machining techniques, such as turning, milling, and drilling. This property makes it ideal for applications that require precision machining.
Weldability: 1035 carbon steel is easily weldable, making it an excellent choice for applications that require welding. It can be welded using common welding techniques, such as TIG, MIG, and stick welding.
Magnetic Properties: 1035 carbon steel is magnetic, which makes it suitable for applications that require magnetic properties.
Heat Treatment: 1035 carbon steel can be heat treated to improve its strength and hardness. It can be hardened by quenching and tempering, which involves heating it to a high temperature and then cooling it rapidly in water or oil.
The chemical composition of AISI 1030 carbon steel is outlined in the following table.
| Element | C | Mn | P | S | More |
| Min | 0.32 | 0.6 | - | - | ①②③④⑤ |
| Max | 0.38 | 0.9 | 0.04 | 0.05 |
① When carbon steel is required to specify the Si content, it is usually selected according to the following five grades: Si≤ 0.10%, 0.10%~0.20%, 0.15%~0.35%, 0.20%~0.40%, 0.30%~0.60%.
② When the content of copper and Cu is specified for carbon steel, Cu ≥ 0.2%.
③ When it is necessary to add lead Pb element to the standard steel, the specified range is 0.15%~0.35% (including 0.35%). Such steel is identified by inserting the letter L between the second and third digits of the grade name, for example 10L45. When lead Pb was added to the ladle, no thermal analysis was performed.
④ When boronization of killed steel is specified, the content of boron in the steel should reach 0.0005%~0.003%. Steel containing titanium is not allowed, and the upper limit of boron content can reach 0.005%.
⑤ When the supply and demand sides reach an agreement, bismuth, calcium, selenium or tellurium can be added to carbon steel.

1035 carbon steel is used for forged parts where the strength and toughness of the material are appropriate. C1035 may be used for the manufacture of links and couplings, gears, forged shafts and axles. It may also be used for the production, by open die forging, of such diverse parts as a 4,000 lb hub for a mining shovel.
