Characteristics and uses cutting structural steel, good accuracy, easy cutting, greatly improve tool life and reduce processing time. Is S-P composite sulfur, low silicon cutting steel. Significantly higher than the low-carbon steel cutting, productivity increased by 30 to 50 percent lower than carbon steel, especially when tapping, tap life more than double than the low-carbon steel, manufacturing unimportant standard parts, such as bolts, nuts , fittings, spring seat and so on.
