This intermediate grade, with its carbon content of 0.15-0.20%, delivers an optimal balance for applications requiring better mechanical performance than standard mild steel without the fabrication challenges of higher-carbon grades. The hot-rolling process ensures good material integrity and consistent mechanical properties throughout the 19-32 mm cross-section, making it an economical choice for structural components, forgings, and general fabrication. --- ## **1.
