Welcome to BBN High Strength Steels Factory
Since it was established in 2000. Based on the domestic rich S550 steel shot product resources and the great steel demand of the international market, our S550 steel shot service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products
Our ogistics department has a professioanl team to support the goods’ transportation and delivery time. Its responsibilities: make customs clearance documents, track products production process, and update shipping information for customers. The company will adhere to the mission of reflecting social values, take the scientific management system as the guarantee of daily operations, and provide continuous technological innovation to support its sustainable development.
The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for S550 steel shot pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common S550 steel shot carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.
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 S550 steel shot 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 S550 steel shot 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.
As to the Chemical composition, the different content is a main on carbon content, while the carbon content of S550 steel shot, A283Gr. D is no more than 0.27% and it is higher than Grade C (≤0.24%) ; as to the mechanical property, the differences are tensile strength and yield strength, while the tensile strength of ASTM A283 Gr.D is 415-550MPa (60-80 ksi) and yield strength of ASTM A283 Grade D is 230MPa (33 ksi).
The S550 steel shot company has established the corporate values of being proud of innovation and winning, and successfully realized the management of corporate culture. In BBN, leaders are not controllers and supervisors, but earnest S550 steel shot teachers, coaches and enthusiastic friends, so that employees can have more democracy, more autonomy, independence and creativity, and the belief of winning.
