The key chemical properties of TMT (Thermo-Mechanically Treated) bars include a balanced composition of carbon, sulfur, phosphorus, and other elements to ensure desired mechanical properties. Carbon content typically ranges from 0.15% to 0.25%, influencing the bars' strength and weldability. Low sulfur and phosphorus levels enhance ductility and corrosion resistance. Additionally, ele... https://bit.ly/3KV51a1
