“…In a study of geometrical factors, Moroishi and Satake [75] assessed the upper and lower sides of CS and WS specimens using specimens with one side painted that were exposed at various angles and directions. The lower side tended to corrode as much as 60-70% more than the upper side, and the extent of corrosion increased as the orientation approached the vertical.…”

Extensive information on the atmospheric corrosion of weathering steel has been published in the scientific literature. The contribution of the present work is to provide a bibliographic review of the reported information, which mostly concerns the weathering steel ASTM A-242. This review addresses issues such as rust layer stabilisation times, steady-state steel corrosion rates, and situations where the use of unpainted weathering steel is feasible. It also analyses the effect of exposure conditions. Finally it approaches the important matter of predicting the long-term behaviour of weathering steel reviewing the different prediction models published in the literature.

NEED FOR WEATHERING STEELRecognition of global warming and environmental degradation has caused the direction of technology to shift toward environmentally conscious and sustainable development, with the result that increased efficiency in the use of limited resources is now a focus (e.g., recycling industrial materials). In addition, the environmental characteristics of industrial products, structures, and materials through their life cycles are being improved by life-cycle assessment (LCA) of the International Organization for Standardization (ISO) 14000s. Although LCA needs further improvement, it is a potentially useful methodology for systematically analyzing a product from the extraction of resources to eventual abandonment, including reuse, recycling, or disposal in terms of energy, in most cases, and materials, emissions of hazardous substances, and wastes.The LCA approach is being used to clarify quantitatively the important role of steel and steel products in our society in terms of their abundant resources, economic availability in large quantities, workability, reliability, reasonable life-cycle cost, relatively low environmental burden, and recycling possibilities.Structural steel is expected to remain as one of most environmentally friendly materials available in the twentyfirst century. In addition, the recent life-cycle study of automobiles, houses, bridges and so on conducted by the Engineering Academy of Japan has demonstrated that 7085% of the energy consumption by these products throughout their life cycle occurs during service period, rather than during production or product assembly [1]. This observation indicates that materials performance, durability, and reliability are key considerations in the design of a product or a structure for its life-cycle energy efficiency. Figure 48.1 shows an example of the framework for the systematic assessment of materials performance, including (a) life-cycle cost (LCC) analysis, (b) life-cycle safety (LCS) design, (c) LCA for energy and materials, and (d) diagnosis of life prediction based on the operating mechanisms.Our living environments consist mainly of freshwater, seawater, the atmosphere, and soil. These four categories include the environments in which the majority of structural steel products and large structures are exposed. Corrosion mechanisms of structural steels and the dominant corrosion parameters in these environments are discussed in other chapters. In this chapter, carbon and low-alloy structural steels resistant to atmospheric corrosion (i.e., weathering steels) are discussed. Weathering steels have been widely accepted i...

The atmospheric corrosion of weathering steel (WS) has been extensively discussed in the scientific literature, but a comprehensive overview of this topic from an engineering viewpoint is currently lacking. The present publication seeks to fill this gap, providing engineers, designers and steel manufacturers with an insight into the current state of knowledge on this important structural material and presenting key research findings in a way that promotes their practical application. The Part I of this review is addressed to various aspects of WS atmospheric corrosion, such as corrosion mechanisms, corrosion products and layers, effect of exposure environment conditions and long term performance. A number of design and metallurgical considerations is also focused.
