1215 free-cutting steel bars are a low-carbon steel highly regarded for their excellent machinability and high production efficiency. The high sulfur and manganese content in this steel allows for the formation of short, easily removable chips during machining, significantly reducing cutting resistance and processing time. This makes it widely used in automatic lathes and the mass production of components.
1215 free-cutting steel bars are an ideal choice for mass production due to their outstanding cutting performance and ease of machining. The high sulfur and manganese content not only enhances the machinability of the material but also effectively extends tool life. During machining, this steel generates short chips that are quickly expelled, reducing cutting forces and processing time, thereby improving overall production efficiency. Although 1215 steel has lower weldability, it excels in turning, drilling, and tapping processes, making it suitable for manufacturing parts that require precise dimensions and smooth surfaces, such as bolts, screws, shafts, and connectors. This material is widely used in industries like automotive parts, mechanical engineering, and electronics, especially in automated production lines and high-efficiency manufacturing environments.
