In recent years, in line with the development trend of iron and A572 Gr 60 high strength steel steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which A572 Gr 60 high strength steel are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
Due to the surge in business volume in recent years. In addition to coordinating our own truck fleet, our logistics department has continuously developed high-quality logistics companies and signed long-term cooperation agreements. While enjoying the professional and fast service of logistics companies, we have significantly reduced transportation costs. That not only ensure our customers receive the goods at the same time, but also help them reduce shipping costs.
Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled A572 Gr 60 high strength steel products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the A572 Gr 60 high strength steel rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.
BBN had provided A572 Gr 60 high strength steel Hardox plates for more than 15 years for widely applied in coal mining machinery, cement equipment, road construction machinery, engineering machinery, dump trucks, metallurgical area and port fields. In 2016,we brought our customer to visit our A572 Gr 60 high strength steel NM400 steel plate producing line and our Shanghai warehouse for 30000 tons plate and structure. As a result, Our client purchased 500 tons NM 400 as first order, which is shipped by 3 times. In future, BBN will always guarantee that all the delivery condition for Hardox plate provided will be with quenching and tempering, which is the best delivery type according GBT 24186 standard.
Q550C steel belongs to low alloy high strength steel. Chemical composition of Q550C steel: C ≤ 0.18, Si ≤ 0.60, Mn ≤ 2.0, P ≤ 0.030, S ≤ 0.030, Nb ≤ 0.11, V ≤ 0.12, Ti ≤ 0.20, Cr ≤ 0.80, Ni ≤ 0.80, Cu ≤ 0.80, N ≤ 0.015, Mo ≤ 0.30, B ≤ 0.004, Al ≤ 0.015. Mechanical properties of Q550C steel: yield strength ≥ 550 MPa, tensile strength 600-780 MPa, elongation after fracture ≥ 16%, impact energy ≥ 55J. A572 Gr 60 high strength steel, Q550C steel is mainly used for manufacturing various large-scale engineering structural components and construction machinery. Due to its high strength, Q550C steel can meet the requirements of large-scale and lightweight construction machinery.
