The company is a leading company that sells A709 Gr 50 structural steel sheet steel plate products in the Central Plains region and has a high reputation in the steel plate industry. Since its establishment, the company has always adhered to the business philosophy of "integrity cooperation and common development", and has sold A709 Gr 50 structural steel sheet steel products with various materials. The products are widely used in petroleum, chemical, construction, boiler, decoration, offshore operations, electric heating, gravity machinery and other industries.
The pipeline steel coil A709 Gr 50 structural steel sheet and plates are our main products. And the most popular standard for pipeline steel is API 5L. We mainly supply API 5L grade B (L245), API 5L X42 (L290), API 5L X46 (L320), API 5L X52 (L360), API 5L X56 (L390), API 5L X60 (L415), API 5L X65 (L450), API 5L X70 (L485) pipeline steel coil and plates. Those stteel grades have both PSL1 and PSL2 levels. PSL2 has more strict requirements than PSL1. Besides, we also supply API 5L grade A PSL1 and API 5L X80 PSL2 steel.
Wear resistant steel plate has high wear resistance and good impact performance. It can be cut, bent, welded, etc. This material A709 Gr 50 structural steel sheet can be connected with other structures by welding, plug welding, bolt connection, etc. Wear resistant steel plate has the advantages of saving time and convenience in the process of maintenance. It is widely used in metallurgy, coal, cement, electric power, mining, building materials and other industries. Compared with other materials, wear resistant steel plate has a high cost performance, and has been favored by more and more industries.
Composition characteristics of low alloy structural steel, A709 Gr 50 structural steel sheet: (1) Low carbon: the carbon content of low alloy structural steel is less than 0.20% due to the high requirements of toughness, weldability and cold formability. (2) The alloy elements such as manganese are added. (3) The addition of Nb, Ti or V and other auxiliary elements: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of low alloy structural steel. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. The addition of a small amount of rare earth elements can remove sulfur and gas, purify the steel, and improve the toughness and process performance of low alloy structural steel.
Hot Rolled Plates Products Testing BBN STEEL can supply many tests and analysis done to examine them before and after the manufacturing. As the A709 Gr 50 structural steel sheet raw material is fetched by us the steel undergoes vacuum treatment, product analysis, additional tensile test, simulated post weld heat treatment, and impact test. After the steel is converted to steel plates they undergo the drop-weight test, hot tensile test, ultrasonic test, the practical examination through examination, and the vacuum carbon deoxidized steel."
Our company has strict quality control standards. If you want to visit our factory, you are welcome at any time! We produce a lot of steel products every month to export A709 Gr 50 structural steel sheet to all over the world. Because our customers are from all countries, they will order a large number of steel products from our company every month.
