What is the difference between CCS A and CCS B? Both CCS A and CCS B are structural steels for general strength hulls. The structural steel for hull is divided into four grades A, B, C and D according to quality. Steel plates belong to general strength plates, and the Mn content of chemical composition is very different, and there is no difference in mechanical properties, yield and tensile strength are the same. The difference is the experimental temperature of the impact energy, the A level is 20℃, and the B level is 0℃.
The company has our own truck fleet, and can transfer products flexibly and quickly. At the same time, we have large warehouses near the ports of Tianjin and Shanghai, so as to ensure that we can deliver high-quality products to customers in the first time. At the same time, it also greatly reduces the transportation cost, and realizes the double harvest of time benefit and economic benefit. Time guarantee is one of the important strengths of our service.
Vanadium is a weak deoxidizer. Adding vanadium into RINA grade A floating dock steel steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.
What is the specific use of RINA grade A floating dock steel, hot rolled plate in daily life? First of all, hot rolled plate is used in bridge, vehicle structure, frame and other fields to play a role of bearing pressure. Secondly, high pressure boiler vessels are also made of hot rolled plates, which can be heat-resistant and airtight, and can stably seal the hot gas in the container. Thirdly, stainless steel hot rolled plate can be used to process hardware products. It has excellent corrosion resistance, and is easy for processing.
