Quality
Mild-steel (MS) cast billet, 100×100 mm, manufactured in accordance with IS 2831:2012 (carbon-steel cast billets for re-rolling into ordinary-quality structural steel). The billet is controlled principally by chemical composition — Carbon (C) ≤0.25%, Manganese (Mn) 0.50–1.00%, Sulphur (S) ≤0.05%, Phosphorus (P) ≤0.05%, Nitrogen (N) ≤0.012% — so that the re-rolled structural steel meets the mechanical requirements: yield strength (ReH) ≥250 MPa, tensile strength (Rm) 410–540 MPa, and elongation after fracture (A) ≥23%. Suitable for re-rolling into reinforcement bar, sections and other ordinary-quality structural products.
