Application Key Technologies of Ferritic Stainless Steel for Traffic Sign Substrate Plate

Abstract:

This paper explains the economy and mechanical properties of the ferritic stainless steel used as the materials of the traffic sign substrate plate, analyzes the relationship between the density of the ferritic stainless steel and the thickness of the substrate plate, proposes a method to determine the quality of the welding, and describes the corrosion mechanism and processing performance of the ferritic stainless steel substrate plate while proposing the related improving ways. The results showed that: by reducing the thickness, ensuring the overall load, adopting the tempering control to reduce the contents of the C, N and other impurities, adding the alloy elements such as the Cr, Mo, Ti, Nb to lower the corrosion, and reducing the C, N, S, P, O and other impurity elements to improve the welding performance, the ferritic stainless steel can be a good material for the traffic sign substrate plate.
