The carbon content of CCS FH32 naval vessels steel, hot rolled steel plate is slightly higher than that of cold rolled steel plate. Hot rolled steel plate has low hardness, easy processing and good ductility. Cold rolled steel plate has high hardness and is difficult to process, but it is not easy to deform and has high strength. The strength of hot-rolled steel plate is relatively low, the surface quality (oxidation finish) is low, but the plasticity is good, and it is generally medium thick plate.
The company has always been adhering to the business philosophy of "integrity-based, responsibility oriented, quality first, reputation first" and is committed to building a world-class steel materials and service provider. We will continue to work hard to carry forward the enterprise tenet of "quality is the life of the enterprise, survival by quality, development by reputation", and become an enterprise with strong vitality! We always keep it in mind that profit is important to enterprises. But what counts more is social responsibility.
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℃.
