Carbon steel mainly refers to the steel whose mechanical properties depend on the carbon content in the A709 Gr 50 bridge steel plate steel, and generally does not add a lot of alloy elements, sometimes it is also called ordinary carbon steel. Carbon steel refers to iron carbon alloy with carbon content of WC less than 2%. In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur and phosphorus. According to the content of phosphorus and sulfur, the carbon steel can be divided into ordinary carbon steel, high quality carbon A709 Gr 50 bridge steel plate steel, high quality steel and super quality steel.
Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;
Sulfur is a very harmful element in A709 Gr 50 bridge steel plate steel. The presence of sulfur will increase the hot brittleness of steel, reduce the various mechanical properties of A709 Gr 50 bridge steel plate steel, and reduce the weldability, impact toughness, fatigue resistance and corrosion resistance of steel.
Structural steel is a category of steel construction material that is produced with a particular cross section or shape, and some specified values of strength and chemical composition. A709 Gr 50 bridge steel plate, Structural steel plates are normally supplied in the as-rolled condition. Our structural steel plate are supplied with thickness range 3mm to 350mm. The plates may be ordered normalized or stress relieved, or both. steel plates shall be normalized. steel plates and sheets shall be quenched and tempered.
