Description

A low-carbon steel, with higher manganese compared to other low-carbon steels, such as 1020. Having a richer manganese content, 1018 is a better steel for carburized parts, since it produces a harder and more uniform case. along with high mechanical properties and better machining characteristics

Applications

1018 has a wide variety of applications. It is used for parts requiring cold forming, such as crimping, swaging or bending. For severe bends, stress relieving may be necessary to prevent cracking. It is highly suitable for carburized parts, such as gears, ratchets, worms, pinions, pins, chain pins, dowels, machine parts, non-critical components of tool and die sets, tool holders, etc. It is used when good workability is required, on parts requiring threading, drilling, punching and machining. It is extensively used for mounting plates, spacers and fixtures. C1018 is suitable for all applications that do not require the greater strength of high carbon and alloy steels.
