Carbon 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.ASME SA709 Grade 50W/SA709 Gr.50W low alloy weathering ASME SA709 Grade 50W/SA709 Gr.50W low alloy weathering steel plates are famous for their property in atmosphere corrosion resistance. They are suitable for application in steel structures especially for building and engineering machinery parts requiring better weldability and toughness.
