The company specializes in the research and development, production and sales of normalised GL-AH 36 heavy steel plate seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has normalised GL-AH 36 heavy steel plate five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,normalised GL-AH 36 heavy steel plate rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.
The company's logistics department has the ability to monitor the whole process of logistics. We monitor the goods in transit through advanced information technology and communication technology, timely discover and handle problems in the transportation process, and ensure the steel materials are delivered to the destination in a timely and safe manner. The professional logistics team provides powerful support for good comments of customers and good reputation of the company.
Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while normalised GL-AH 36 heavy steel plate steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of normalised GL-AH 36 heavy steel plate steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
BBN steel had provided Grind plates for more than 15 years for widely applied in equipment, Engineer machinery etc. In 2018, one of our India customer visit our normalised GL-AH 36 heavy steel plate office and work shop to discuss Q235B Grind plate technical request, they have strict surface and thickness tolerance, and they also request UT and MT for testing. As a result, they purchase normalised GL-AH 36 heavy steel plate 179 tons as trial order for first cooperation. And have good comment on our quality. Till now, we keep exporting around 100 tons per month as regularly.
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, normalised GL-AH 36 heavy steel plate, 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.
Company management philosophy: integrity-based, service-oriented, excellence, affinity symbiosis. Based on quality, continuously create maximum value for customers. Always have a grateful heart, thank the society, thank family and friends for their support and help to the development of the company, thank customers for their trust, thank colleagues for their cooperation, and thank competitors for their supervision.
