Resumo
Checkered plate, which is also known as floor plate, has a raised pattern that provides excellent skid resistance for a wide range of applications, such as flooring, walkways, platforms, stair treads, covers, etc. As one of most common used products, carbon steel checkered plate needs high cost in corrosion resistance. Although stainless steel checkered plate meets the requirements of corrosion resistance, it is also hard to provide a highly comprehensive performance for its low mechanical properties, which mean higher thickness, higher weight, lower stability of structure. Combined the advantages of stainless steel and carbon structural steel, one kind of SUS316L-BDT01 or SUS304L-BDT01 roll-bonded clad checkered plate with high performance in skid resistance, high strength and corrosion resistant is developed. The metallography shows cladding interfaces are very good. The yield strength, tensile strength and elongation from tensile tests are significantly better than the other kinds of checkered plates. Both external and internal bending at room temperature can be done successfully done without any cracks. Therefore, roll-bonded clad checkered plate shows superior performance in microstructure, strength, ductility and workability. It will meet the requirements of modern factories and has a broad market prospect. Through a case of the application on a pulverized coal injection platform in an iron-making plant, the processing and installation of this kind of material were introduced. After two years tracking on the platform, the product shows high performance in corrosion resistance and mechanical properties.
