Welcome to BBN High Strength Steels Factory
Our company was founded in 2000, which initially committed to providing high-quality steel S460QL steel products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export S460QL steel steel to the international market, opening up the international steel market.
Tianjin warehouse mainly stores steel plates and steel pipes. The monthly replenishment is about 12000 tons. Our inventory cycle is short and flexible. Shanghai warehouse mainly stores S460QL steel ,steel plate and section steel. The average monthly purchase volume is about 15000 tons. The geographical location of the warehouse has greatly improved our performance in terms of transportation and delivery time.
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 S460QL steel, 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.
Bangladesh is an important market to us. We cooperated with the National Railway, the National Tubes Limited (NTL) and so on state-owned enterprises. They have tenders regularly. And we would participate the tenders with our local agents. We have been the winner of NTL tenders for many times. API 5L grade B steel strips are their needed S460QL steel materials. They have special chemical composition, tolerance and so on requirements. We can fully meet their demands and guarantee timely delivery.
S460QL steel, API 5L X52 steel with the thickness range is 1.2-40mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. API 5L X52 steel’s mechanical properties is the yield strength 300MPa, and the tensile strength 460MPa. To be specified in details: Maximum content for C≤0.28%, Mn≤1.4%, P≤0.030%, S is 0.030%, V+Nb+Ti≤0.15%, Copper maximum is 0.50%, nickel maximum 0.50%, chromium 0.50%, Molybdenum 0.15%.
Management concept: abide by laws, regulations and social norms. To improve the system of management, to carry out activities with high corporate ethics. Mutual respect, unity and harmony, create a "fair, just and open" good working environment for employees.
