Vergleichende Beurteilung neuartiger umweltgerechter Korrosionsschutzsysteme fur den Stahlbau durch Langzeitlagerungen und Labor-untersuchungen
This study reviews the protection offered to construction steels in different circumstances by a) traditional pigment materials such as red lead and zinc chromate and more recently developed alternatives b) alternative coating systems using water-based materials or reaction-type resins or c) zinc-dust and other like systems. One result was the synergistic effect of low-level alloy elements in combination with supplementary treatment with the same elements, e.g. Cu and Cr. - especially over a long period. A significant alternative system is the use of hot-zinc treated steel with a coating (the duplex system) - but not for atmospheres contaminated with nitrogen and sulphur oxides. Another possibility is the combination of stainless-steel with less than 12% Cr and a coating treatment which in some circumstances can replace galvanized steel. The non-rusting steel X2CrNi12 has the highest consumption growth rate and is preferred for situations where loss of mass must be minimized but in coastal areas, a coating is essential. The study also compared the corrosive effects of long-term weathering and accelerated treatment over a wide range of different steels
