Free-cutting steel
Free-cutting steel
Our carbon steels are added free-cutting elements such as sulfur, lead, and tellurium to improve machinability.
We have a variety of steel materials that meet usage and requirements.

Pb-free free-cutting steel
Pb, which affects machinability, is also an environmentally hazardous substance.
Pb-free steel is a free-cutting steel that has improved machinability without adding Pb.
