易切削钢管由高切削加工性钢种制成，结合了良好的强度和优异的切削性能。这些管材适用于精密车削、钻孔或螺纹加工，是生产高精度圆柱形零件的理想选择。

Free cutting steel bars are specially designed materials that offer superior machinability. By adding elements such as sulfur, lead, or phosphorus, the steel's cutting performance and chip-breaking ability are improved, enabling high-speed and precise machining. They are widely used in automatic lathes and CNC machining centers for mass production of precision components.
