1214 free-cutting steel bars

12L14 free-cutting steel bars are a low-carbon steel with a high lead content, widely recognized for their excellent machinability and processing efficiency. The addition of lead allows for the formation of short chips during machining, reducing cutting forces and extending tool life. This makes 12L14 ideal for mass production of components such as bolts, screws, and shafts.

12L14 free-cutting steel bars are an ideal material for many manufacturing industries due to their superior machinability and efficiency. The inclusion of lead enhances the material’s lubricity, significantly reducing friction and cutting forces during machining, thereby improving overall processing efficiency. Moreover, 12L14 steel offers excellent dimensional stability and surface finish, maintaining high-quality results even at high machining speeds. While its weldability is relatively low, its outstanding machinability compensates for this, making it widely used in the production of parts requiring precise dimensions and smooth surfaces, such as bolts, screws, valve components, and shafts. 12L14 steel is particularly well-suited for use in automatic lathes and continuous production lines, with broad applications in industries like automotive manufacturing, mechanical engineering, and electronics.
