11SMn30 free-cutting steel bars are low-carbon steel specifically designed for efficient machining, known for their excellent cutting performance due to their high sulfur content. This material produces short, easily removable chips during processing, greatly enhancing machining efficiency. It is widely used in the manufacturing of precision parts such as screws, bolts, and components on automatic lathes.
11SMn30 free-cutting steel bars are renowned for their exceptional machinability, particularly excelling in automated machining and high-volume production. The high sulfur content not only aids in the quick removal of chips but also reduces cutting forces, extending tool life, and thereby improving production efficiency and reducing machining costs. Additionally, 11SMn30 offers good surface finish quality, maintaining high standards even under high-speed machining conditions. While its corrosion resistance is relatively low, the material’s outstanding mechanical machining properties make it a preferred choice for manufacturing parts requiring precise dimensions and smooth surfaces, such as shafts, screws, bolts, and connectors. It is extensively used in industries like automotive manufacturing, mechanical engineering, and electronic equipment.
