Y15 cutting steel
Y15 is cutting structural steel, good accuracy, easy cutting, greatly improve tool life and reduce the process time increases. Is S-P composite sulfur, low silicon cutting steel. Cutting significantly higher than Y12, productivity increased by 30 to 50% higher than Y12 steel, especially when tapping, tap life than Y12 raise more than twice.
       Purpose: Standard Parts Manufacturing unimportant, such as bolts, nuts, fittings, spring seat, etc.
       Mechanical properties:
