Abstract

The machinability of plain carbon or low alloy steel is improved by the addition of certain elements so that they are present within the following percentage ranges: <TABS:1020423/C6-C7/1> A free machining steel so produced contains: C not more than 0.13; Mn 0.8-1.2; P 0.04-0.09; the above elements in the ranges specified and Fe and impurities, the balance.
