Strength: 1040 carbon steel has moderate strength, making it suitable for applications that require moderate mechanical strength. It has a minimum tensile strength of 620 MPa and a minimum yield strength of 355 MPa.
Ductility: 1040 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: 1040 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: 1040 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: 1040 carbon steel is magnetic, which makes it suitable for applications that require magnetic properties.
Heat Treatment: 1040 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 1040 carbon steel is outlined in the following table.
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.
AISI 1040 carbon steel can be used in couplings, crankshafts, and cold headed parts.
