Cutting steel is added to elemental sulfur in the steel, it has easy cutting, in order to produce goods suitable for machining with automatic hot-rolled and cold-drawn steel bars. Such steel can be larger with a higher cutting speed and cutting depth of the cutting. Added in the steel cutting element, the cutting resistance of steel decreases, also act as the lubricating properties of the cutting tool cutting element itself, and the compound formed by the frangible debris, reducing wear and tear, thereby reducing the surface of the workpiece roughness improves tool life and productivity. With the continuous development of mechanical cutting to automated, high-speed and precision of the direction of the cutting of the material put forward higher requirements, so there better machinability lead a sulfur compound cutting steel, also known as super-easy cutting steel. After various lead a sulfur binary and multiple composite cutting steel have come out.
