Cold Rolled Flat Bars

1018 Cold Finished Bars
ASTM A 108 UNS G10180

A low-carbon steel, having higher manganese content than certain other low-carbon steels, such as 1020. Being richer in manganese, 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.

Suitable for parts requiring cold forming, such as crimping, or bending. However, for severe bends, stress relieving may be necessary to prevent cracking. Especially suitable for carburized parts requiring soft core and high surface hardness, such as gears, pinions, worms, king pins, chain pins, ratchets, etc.

1018 has a machinability rating of 78%, based on 1212 as 100%. Average surface cutting speed is 130 feet per minute.

This grade is easily welded by all the welding processes, and the resultant welds and joints are of extremely high quality. The grade of welding rod to be used depends on the thickness of section, design, service requirements, etc.
