Welcome to BBN High Strength Steels Factory
In recent years, in line with the development trend of iron and flat 50x10 S690QL 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 flat 50x10 S690QL 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.
In the process of flat 50x10 S690QL steel transportation, enterprises often use railway transportation, highway transportation, water transportation and other ways to transport. According to the cargo owner's requirements on the timeliness of the goods and the different transportation routes, our company will choose flat 50x10 S690QL different modes of transportation. According to the specific needs of customers, or specify the mode of transportation.
BBN Group's first blast furnace blast dehumidification system: The project started construction on May 2 and began trial operation on August 28. All data are balanced and stable, blast furnace output indicators have improved significantly, and the daily dehydration capacity of the two blast furnaces is as high as 124 tons, with a daily increase of about 200 tons flat 50x10 S690QL, and the blast furnace is running smoothly.
our company supplied 2300 ton API 5L GrB ERW pipe to Petroleum company in 2016. It takes 35 days for our company to finish all the production according to API 5L standard. The products are used to drilling , gas transmission works. And we supply the API5L PSL1 GR B original Mill Test Certificate, API5L PSL1 GR B pipes picture, the dimension test, the flat 50x10 S690QL material, heat number, supplier name and size will be shown on the surface of steel pipe.
Chemical composition of Q420 steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420 steel are: yield strength ≥ 340 MPa, tensile strength 500-680 MPa, elongation after fracture ≥ 18%, impact energy 34J. flat 50x10 S690QL, Q420 steel has good mechanical properties and weldability, good cold and hot workability. Q420 steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts.
