Carbon steel balls offer the precise geometry and fine surface finish that makes them especially useful for bicycles, casters, drawer slides, door locks and many other applications.  AISI 1015 is a low-carbon steel that offers superior workability and machinability. A versatile engineering and machinery alloy, AISI 1015 is used normalized, hot-rolled, cold-worked or annealed.
