In recent years, there has been a significant increase in demand for color coated steel plate products with high strength, high toughness, and good formability in the domestic and foreign color coated steel plate markets, and at the same time, the requirements for cost control have also continued to increase. In response, Baosteel has successfully developed products with high strength and toughness
Advanced high-strength steel color coated steel plate products mainly utilize the principle of phase transformation strengthening, and can obtain advanced high-strength color coated steel plate products with high strength, high toughness, processing and forming properties, and good plate shape without increasing or reducing costs, better meeting the performance requirements of users for different steel grades.
Reasonable material selection can not only meet the usage requirements, but also greatly reduce costs. If the material selection is improper, the result may be that the material performance exceeds the usage requirements, causing unnecessary waste; It may also be due to failure to meet usage requirements, resulting in degradation or inability to use. Therefore, the purchaser should attach great importance to the importance of reasonable material selection and consult relevant experts when necessary. E. The selection of 2 color coated boards mainly refers to the selection of mechanical properties, substrate type and coating weight, front coating performance, and back coating performance. Important factors to consider when selecting materials include usage, corrosiveness of the operating environment, lifespan of the first major repair, durability, processing method, and degree of deformation. E. 3. Selection of mechanical properties, substrate type, and coating weight E.3.1 Mechanical properties are mainly selected based on factors such as usage, processing method, and degree of deformation. When the strength requirement is not high and the deformation is not complex, TDC51D and TDC52D series color coated boards can be used. When there are high requirements for formability, TDC53D and TDC54D series color coated boards should be selected. For components with load-bearing requirements, suitable structural steel should be selected according to design requirements, such as TS280GD and TS350GD series color coated plates. Cutting, bending, rolling, and other commonly used processing methods for color coated panels should be selected based on the characteristics of each processing method when ordering. In actual production, the mechanical properties of the substrate are usually replaced by the mechanical properties of the color coated board, and the color coated process may cause changes in the mechanical properties of the substrate. In addition, mechanical properties may also change with increasing storage time. These will increase the possibility of Luedes bands or creases appearing during the processing and forming of color coated panels, and attention should be paid to this. E. 3.2 The type of substrate and the weight of the coating mainly depend on the purpose and corrosiveness of the usage environment
