Mainly for the production of smaller and force size and finish demanding instrumentation, watch parts, automobiles, machine tools and various other machines used for dimensional accuracy and finish demanding, while the mechanical performance requirements are relatively low standard parts, such as gears, shafts, bolts, valves, bushings, pins, fittings, spring seat and machine screw, plastic mold, surgical and dental surgery and other appliances.

Edit this section describes
12L14 is cutting structural steel, free cutting steels are susceptible (turning, milling, pull, planing, drilling, etc.) machining of steel, also known as automatic machining of steel, referred to as auto steel. It is to adapt machining automation and assembly-line production line produced. Such steel can be relatively high speeds and the amount of cut for deeper cutting, and due to the addition of the steel cutting element and the cutting resistance is reduced due to addition of the compound from the characteristics of the element itself and the lubrication of the tool edge is formed acting portion, so that the chip easily broken, reducing the wear and to improve the accuracy by finish machining of parts, to improve tool life and productivity.
12L14 sulfur compound belonging to lead cutting structural steel. Lead free cutting steel, the lead in the tiny elemental metal particles distributed in the steel and non-solid melting in steel, in the cutting process, resulting in a strong friction between the tool and the work piece, the steel was melted lead particles precipitation, and thus play a role in improving the lubrication cutting steel, steel crushing the chips, reduce tool wear, and ultimately extend tool life. Compared with the lead-free steel, leaded cutting steels can be increased from 20 to 50%, while the mechanical properties and heat-treated properties remained unchanged, cold, hot workability and weldability are not affected. Lead free cutting steel has been widely used in the manufacture of precision instrument parts, auto parts, important parts of various types of machinery. But contact fatigue lead free cutting steel is low, it is not appropriate to withstand fatigue stress load large gears, bearings and other parts.
12L14 has been replaced by its trend. Its cutting performance is also very good. Applicable to the case of more stringent 12L14 not be used. [1]
