AR(As Carbon and low alloy steel plate - BBN SteelCarbon and low alloy steel also known as Mild steel. steels with a low carbon content and without alloy are softer and more easily formed, it is a low-cost material that is easy to shape. While not as hard as higher-carbon steels, carburizing can increase its surface hardness. carbon structural steel has the proper tensile strength, good toughness, plasticity, processing property.
