12L14 is a type of resulfurized and rephosphorized carbon steel for free-cutting and machining applications. The structural steel (automatic Steel) has excellent machinability and lower strength due to the alloying elements like Sulfur and Lead, which can reduce cutting resistance and improve the finish and precision of machined parts. 12L14 steel has been widely used in the manufacture of precision instrument parts, automobile parts and important parts of various kinds of machinery, typical applications including bushings, shafts, inserts, couplings, fittings and etc.
