The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating A131 AH36 naval engineering steel production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.
Medium thick plate refers to the steel plate with a thickness of 4.5-25.0mm. Those with a thickness of 25.0-100.0mm are called thick plates, and those with a thickness of more than 100.0mm are extra thick plates. Medium thick plate A131 AH36 naval engineering steel is a kind of flat steel with large width thickness ratio and surface area. The main materials of medium thick plate are Q235, Q345, S355JR, etc. The company not only provides raw steel materials, but also provides cutting and so on processing services for medium and thick plates, extra thick plates and wide and thick plates.
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 A131 AH36 naval engineering steel 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 A131 AH36 naval engineering steel 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.
The wear-resistant plate A131 AH36 naval engineering steel shows good wear resistance: the chemical composition of the alloy layer contains 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%, the macro hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Because of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and A131 AH36 naval engineering steel hardness is more than twice as that of the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 1.5-2.5:1.
From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%. We promise that every order will be tracked in a timely manner to ensure that customers can receive goods safely and constantly listen to their opinions and suggestions, reflect on our own problems, and let customers feel at ease. We have a large warehouse in Shanghai and Tianjin, which can provide customers with sufficient sources of supply.
Our products have perfect after-sales system to protect the interests of customers. At the same time, we can according to A131 AH36 naval engineering steel customer's requirements, processing requirements, cutting technical requirements, etc., to develop detailed solutions for customers, so as to make customers 100% satisfied.
