Product Details

12L14 is a type of American standard lead - sulfur free - cutting structural steel (Automatic Steel). Alloyed elements in free-cutting steel like Se, lead can reduce cutting resistance and improve the finish and precision of machined parts. Lead in 12L14 steel is distributed with small particles and is not solid melting in the steel. During the cutting process, the tool and the workpiece produce strong friction, which makes the lead particles in the steel melt out and improves the cutting performance of the steel. The cutting performance of leaded steel can be improved by 20~50% compared with that of lead-free steel. Lead cutting steel has been widely used in the manufacture of precision instrument parts, automobile parts and important parts of various kinds of machinery.
