Overview

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.

Forming Methods

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.
