The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel JIS carbon steel SM490YB CS plate products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the JIS carbon steel SM490YB CS plate market and has strong competitiveness.

BBN company is a modern enterprise integrating steel producing, warehousing and logistics, processing and distribution. We are committed to creating a "one-stop steel procurement service" platform. The main products are I-beam, angle steel, JIS carbon steel SM490YB CS plate , H-beam, hot-rolled coil, welded pipe, spiral pipe seamless pipe and many other steel products. Standing stocks amount to more than 30,000 tons, and complete specifications, the company gradually moves towards large-scale distribution enterprises with serialized products, standardized services and modern transportation management.

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 JIS carbon steel SM490YB CS plate 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 JIS carbon steel SM490YB CS plate 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.

The Indian customer purchased our A516 Gr 70 pressure vessel steel plates to make tanks. They have very strict requirement for raw materials quality. For the A516 Gr 70 pressure vessel steel plates, they asked for Normalizing, 0℃ impact, A578 UT test, PWHT and so on tests, our Q/C department witness the production process with the technician from the customer company together. Meanwhile, we arrange BV inspection to check the quantity, spray mark, stamp on the A516 Gr 70 pressure vessel steel plates, and so on.

As to the Chemical composition, the different content is a main on carbon content, while the carbon content of JIS carbon steel SM490YB CS plate, 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).
