Since its establishment, the company has always adhered to the enterprise spirit of "solid feet and lofty ideals, dare to create and take responsibility, and dedicate to work". After years of careful management, the company has achieved the double improvement of A514 grade M alloy steel plate capital strength and scale expansion, gained wide recognition and general praise from all walks of life, further realized specialized and large-scale operation and optimized allocation of resources, and effectively improved the A514 grade M alloy steel plate overall strength, competitiveness and anti risk ability of the company.
The company has a mature technical team whose reponsibility is to design the drawing, choose suitable material and evaluate the whole production processaccording to customers’ requirement. The company is led by talents and technology, and comprehensively promotes its six business segments like steel material supply, precision steel casting, environmental protection equipment, household appliance, A514 grade M alloy steel plate steel structures and oil tank projects. Seeking new developments in new technology and business areas, and fostering a large number of industry-leading, international-level projects.
The difference between alloy steel plate and carbon steel has the following points. First, the hardenability of carbon steel is low, and the maximum diameter of water quenching of carbon steel is only 10 mm to 20 mm; second, the strength of carbon steel is only 235 MPa, while that of alloy steel is more than 360 MPa. Third, carbon steel has poor tempering stability. In order to ensure high strength, low tempering is used for carbon steel during quenching and tempering treatment, so the toughness of the carbon steel is insufficient. Fourth, the corrosion resistance, low heat resistance, and wear resistance of carbon steel cannot be compared with alloy steel, A514 grade M alloy steel plate.
Compared with ordinary steel, the A514 grade M alloy steel plate special steel has the following characteristics. First, the special steel has better physical properties, higher strength, stronger compressive strength, and better precision. Second, the special steel has better chemical properties, such as high temperature resistance, low temperature resistance and corrosion resistance. Third, the composition of the special steel is more diversified, which can be synthesized by integrating other elements, such as alloy steel, high carbon steel, etc. Fourth, special steel is more flexible for processing.
"ASTM A516 Grade 70 plate is a boiler / pressure vessel quality of steel plate for use in low to moderate services. It has improved notch toughness. A514 grade M alloy steel plate, A516 Grade 70 steel plates can be produced with thick up to 200mm.For boiler steel plate A516 Grade 70, the yield strength shall be above 260 Mpa, tensile strength from 485 Mpa to 620 Mpa.A516 Garde70 steel plate is equivalent to the P355GH and 490B grades. "
Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, A514 grade M alloy steel plate sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
