Abstract：Through the design and control of reasonable chemical composition, total oxygen content of steel, w(Mn)/w(S)ratio, w(Te)/w(S)ratio and heating temperature, an environmentally friendly 1214Te free-cutting steel containing sulfur and tellurium was successfully developed, and the process was carried out. Metallographic microscope, scanning electron microscope and energy spectrometer were used to observe and analyze the sulfide inclusions in 1214Te disk and 1215MS disk, which showed that most of the sulfide inclusions in the 1214Te rolled product were spindle-shaped or ellipsoid, and most of the sulfide inclusions in the 1215MS rolled product were long strip. Under the same cutting condition, the chip breaking effect of 1214Te rolled product was better than that of 1215MS rolled product, and the surface roughness of 1214Te rolled product after cutting was reduced.
