Carbon and Low-alloy Steel Despriction

Carbon Steel provide greater environmental corrosion resistance and are stronger than convention carbon steel,also very ductile, highly formable and easy to weld.Carbon Steel steels are not typically made to meet a certain chemical composition, instead they are known to meet specific mechanical properties. Carbon Steelspecification is intended primarily for use in structural members, where savings in weight and added durability are critical.Our Carbon Steel main steel grade: S355JR,A572Gr.50,St52-3,SM570.

Carbon and low alloy 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. Carbon structural steel usually be rolled into steel plates, shaped steel and profile steel, which usually used to build workshop, bridge, vessels and so on .The delivery station usually are hot rolled, control rolled, or Normalized .

Low carbon steel is usually made into flat-rolled sheets and strips, used for shipbuilding, wire, vehicle bodies and domestic appliances. It’s widely used for fabrication and panelling because it can’t be altered by heat treatment. Medium carbon steel is a lot easier to machine and adding small amounts of silicon and manganese improves the quality. Also called mild steel, it’s commonly used structurally in buildings and bridges, axles, gears, shafts, rails, pipelines and couplings, cars, fridges and washing machines. High carbon steel has a much better tensile strength, used to make cutting tools, blades, punches, dies, springs and high-strength wire.
