Abstract

PURPOSE: To provide a nonmagnetic high Mn steel contg. C, Si and Mn as essential elements and one or more out of S, Pb, Se and Te and having high machinability while maintaining the characteristics of high Mn steel.
CONSTITUTION: The free-cutting nonmagnetic high-Mn steel contains C≤2.0%, Si≤2.0% and Mn 7W40% as essential elements and one or more out of S 0.04W 0.20%, Pb 0.03W0.30%, Se 0.03W0.30% and Te 0.005W0.20% as machinability improving elements. This steel has superior machinability, and it can elongate the endurance life of a carbide tool by about 2W4 times and that of a high-speed steel drill by about 5W60 times as compared to a commercially available alloy. In addn., it exhibits superior corrosion resistance as well as high weldability and is suitable for use as a structural material.
