12L14 steel belongs to lead-sulfur composite free-cutting structural steel.In lead-cutting steel, lead is distributed in the steel as tiny metal particles and is not fusible in the steel. In the process of cutting, strong friction between the tool and work-piece, so that the lead particles in steel melt precipitation, so as to improve the lubrication of steel cutting performance, so that the steel chip is fine, reduce tool wear, and finally extend tool life.
