1018 carbon steel is the most commonly available of the cold-rolled steels, it has a good combination of all of the typical traits of steel - strength, some ductility, and comparative ease of welding and machining. Chemically, it is very similar to A36 Hot Rolled steel, but the cold rolling process creates a better surface finish and better properties. 1018 steel high manganese low carbon penetration steel, alloy structural steel is widely used in pistons, screws, drive shafts, machine tools, springs, push plates, lock wedges, female mold sleeves, reset rods, larger diameter push rods, Core fixing plate and other structures.
The chemical composition of AISI 1018 carbon steel is outlined in the following table.

Strength: 1018 carbon steel has moderate strength, making it suitable for applications that require moderate mechanical strength. It has a minimum tensile strength of 440 MPa and a minimum yield strength of 370 MPa.
Ductility: 1018 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.
Weldability: 1018 carbon steel is known for its excellent weldability, making it a popular choice for welding, brazing, and soldering. It can be welded using common welding techniques, such as TIG, MIG, and stick welding.
Machinability: 1018 carbon steel has excellent machinability, which means that it can be easily machined using common machining techniques, such as turning, milling, and drilling.
Magnetic Properties: 1018 carbon steel is magnetic, which makes it suitable for applications that require magnetic properties.
Corrosion Resistance: 1018 carbon steel is not known for its corrosion resistance and may require additional treatments or coatings to prevent corrosion.

Heat treatment, quenching rate and temperature used when drawing or rolling the steel all affect the microstructure of the steel. Forming methods significantly affect the steel's physical properties, including its hardness, tensile strength and ductility. For example, by cold drawing 1018 steel instead of hot rolling it, the machinability of the material can be increased from 52 to 70 percent. Forming methods do not impact the steel's electrical or thermal properties such as resistivity or specific heat.
