Abstract: The process flow sheet for pilot commercial production of free cutting steel SY12SnS (/% : 0.08-0.16C, ≤0.15Si, 1.00-l.30Mn, 0.03-0.07P, 0.15-0.25S, 0.12-0.18Sn) is 100 t DC EAF-LF-195 mm x 195 mm CC- CR (finished product-Φ8 mm). Results show that total amount of large scale inclusions in casting billet of free cutting steel SY12SnS is 4.72 mg/10 kg, HB hardness value o£ rolled products is 134-141, and the tensile strength, elongation and reduction of area of steel are respectively 490-503 MPa, 21.8%-25.0% and 55.4%-56.1% , and the steel has nice turning performance.
