The company adheres to the customer philosophy of "customer first, pursuit of excellence". With the service tenet of "low price, excellent quality, fast transportation and constant commitment", we are committed to providing A131 grade B steel wide flats high quality and timely steel products and services for steel users all over the world. And created a good customer reputation. The main products of the company are section steel, steel pipe, thin plate, rolling plate, medium and thick plate, etc.
The company produces and export steel plates and steel section products of various materials all year round. The width of the A131 grade B steel wide flats thin plate is 500 - 1500 mm; the width of the thick plate is 600 - 3000 mm. Steel plates are classified by steel type, including ordinary steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, etc .; according to use, there are shipbuilding plate, pressure vessel plate, wear resistant steel plate, bridge builidng steel, corten steel plate, and pipeline steel plate.
Bridge steel plate is specially used for erecting railway or highway bridges. A131 grade B steel wide flats, bridge steel plate is required to have high strength and toughness to bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The bridge steel plate used for bolt welding bridge should also have good welding performance and low notch sensitivity.
We BBN steel company have in-house machining capabilities with excellent machining experience. CNC machining-technology, We provide A131 grade B steel wide flats plate products both conventional and CNC machining services to offer the following machined processes :lathe turning, milling, up to 5 axis cnc, grinding, surface, od and id, threading, single point and grinding, drilling, reaming, and tapping, boring.
Chemical composition of 42CrMo seamless steel pipe: C: 0.38-0.45, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.90-1.20, Mo: 0.15-0.25, V: 0.15-0.30. Mechanical properties of 42CrMo seamless steel pipe: tensile strength: 1080 MPa, yield strength: 930 MPa, elongation after fracture: 12%, reduction of area: 45%, impact energy: 63J. Due to the effect of carbon and chromium content, A131 grade B steel wide flats, 42CrMo seamless steel pipe has better strength and hardenability, higher fatigue strength and resistance to multiple impact after quenching and tempering, good impact toughness at low temperature and no obvious temper brittleness. It is generally used after quenching and tempering.
The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.
