Abstract
PURPOSE: To increase the machinability of a machine structure steel and to enable cold forging at a high reduction ratio by regulating the S content and adding a specified amount of Pb.
CONSTITUTION: This machine structural steel having superior machinability and discharging cutting chips easy to treat is obtd. by adding 0.02W0.12% Pb and regulating the S content to ≤0.004%. This steel can be cold forged at ≥70% maximum reduction ratio.
