Welcome to BBN High Strength Steels Factory

Full size range S500Q stahl

Based on the advantages of S500Q stahl steel resources in domestic market and good reputation, combining with the huge international market demand for steel products, our company started the international business in 2010 and successfully being approved and certified by ISO9001:2008, the Registration number is 626014Q11531R0S. With the quality steel S500Q stahl products and professional service, our company was award the international acclaim from infrastructure, shipbuilding, petroleum industry etc., and gradually grow into a bright star in the steel export industry .

Our ogistics department has a professioanl team to support the goods’ transportation and delivery time. Its responsibilities: make customs clearance documents, track products production process, and update shipping information for customers. The company will adhere to the mission of reflecting social values, take the scientific management system as the guarantee of daily operations, and provide continuous technological innovation to support its sustainable development.

In order to easily and economically perform hot or cold processing to make various parts of engineering structures, the low alloy high strength steel must have appropriate forming properties. Like S500Q stahl, carbon structural steel, low alloy high strength steel can generally be processed in such way, as well as cutting, punching, and machining. Although the yield point of low alloy high strength steel is high, even if the forming operation is deformed quite severely, cold bending presses, drawing machines, presses and other equipment used for carbon structural steel forming can also be used for low alloy high strength steel, but some equipment needs to be modified.

We supply 3500 tons SA387GR5CL1 steel plates to Pakistan. The main businesses of the Pakistan customer are manufacturing columns & towers, heat exchanger, waste heat recovery boiler, pressure vessel & reactors, tanks, etc. We arranged SGS test for the SA387GR5CL1 steel plates. The test contents include chemical composition analysis, tensile test, impact test, etc. The test results are satisfied. The Pakistan customer gave good feedback after receiving the SA387GR5CL1 steel plates.

Composition of low alloy steel plate: Low carbon: due to the high requirements for toughness, weldability and cold formability of low alloy steel plate, the carbon content is not more than 0.20%; manganese is added; the auxiliary elements such as niobium, titanium or vanadium are added; a small amount of niobium, titanium or vanadium forms fine carbide or carbonitride in the steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of low alloy steel plate; in addition, The corrosion resistance of S500Q stahl, low alloy steel plate can be improved by adding a small amount of copper (< 0.4%) and phosphorus (about 0.1%).

The S500Q stahl company has established the corporate values of being proud of innovation and winning, and successfully realized the management of corporate culture. In BBN, leaders are not controllers and supervisors, but earnest S500Q stahl teachers, coaches and enthusiastic friends, so that employees can have more democracy, more autonomy, independence and creativity, and the belief of winning.
