Alloy 1018 is the most commonly available of the cold-rolled steels. It is generally available in round rod, It has a good combination of all of the typical traits of steel – strength, some ductility, and comparative ease of machining. Chemically, it is very similar to A36 Hot Rolled steel, but the cold rolling process creates a better surface finish and better properties.
A low-carbon steel, having higher manganese content than certain other low carbon steels, such as AISI 1020. Being richer in manganese, AISI 1018 is a better steel for carburized parts, since it produces a harder and more uniform case. It also has higher mechanical properties and better machining characteristics. The hot rolled bars used in the manufacture of this product are of special quality.
Most cold finished bars are produced by cold drawing. In this process, oversize hot rolled bars, which have been cleaned to remove scale, are drawn through dies to the required size. The larger sizes are generally turned and polished, the hot rolled bars having been machine turned, rather than drawn, followed by abrasive polishing. Turned and polished bars tend to have a somewhat brighter finish than cold drawn bars.
Suitable for parts requiring cold forming, such as crimping, bending, or swaging. Especially suitable for carburized parts requiring soft core and high surface hardness, such as gears, pinions, worms, king pins, ratchets, dogs so on.
