BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of A572 grade 50 carbon steel plate sheet steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main A572 grade 50 carbon steel plate sheet production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.

As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's A572 grade 50 carbon steel plate sheet steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole A572 grade 50 carbon steel plate sheet steel transportation industry.

S355J2 steel plate A572 grade 50 carbon steel plate sheet rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the A572 grade 50 carbon steel plate sheet single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.

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 A572 grade 50 carbon steel plate sheet 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 A572 grade 50 carbon steel plate sheet 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.

SA516Gr.70 steel chemical composition (%):C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45. ASME SA516Gr.70 material is a carbon steel grade for medium and low temperature pressure vessels. In order to meet the different requirements of users and facilitate production management, the S and P requirements of steel grades are divided into three levels of Ⅰ, Ⅱ and Ⅲ. A572 grade 50 carbon steel plate sheet, SA516Gr.70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels.
