Product brief introduction

1144    Is carbon free cutting steel in high sulfur, good cutting performance, compared with 45 # steel can be improved more than four times the knives' service life, improve the production efficiency is 30%, have higher strength and hardness, is suitable for machining parts of high rigid requirements, such as screw, polished rod, rack and spline shaft, etc.
Shape diversity - through the design specifications for different shapes of mold, cold drawn out different cross section shape, different specifications and tolerances of easy cutting steel.
Angle can be a right Angle or rounded.
