This article deals with the topic of atmospheric corrosion. Atmospheric corrosion causes damage to nearly 80% of all existing steel structures. The main parameters of atmospheric corrosion are the time of wetness (TOW), air temperature and aggressive corrosive agents such as chlorides, sulfur dioxide and others. Currently, low alloy steels with improved atmospheric corrosion resistance called weathering steels are used for the steel structures located in outdoor environment. A protective layer of corrosion products is created on the steel surface and this layer can reduce continuation of corrosion of steel. The time of wetness together with the effect of aggressive corrosive agents are various for surfaces oriented vertically or horizontally. Experimental tests of atmospheric weathering steel were carried out to monitor the impact of location and position of surface on the different constructions. These tests allow monitoring the development of corrosion products in real exposures. The article presents a part of the research, which includes monitoring the development of the thickness of corrosion products with regard to the position on the structure. Research is developed to refine of prediction models with the aim of improving determination of corrosion losses during the service life of the structure. Second part of these experiments is dedicated to measuring the deposition rate of chlorides. Chlorides have a corrosive impact on the steel surface. Under normal conditions the chlorides does not create suitable environment for the development of a protective layer of corrosion products.

“…This kind of WS will be extensively used because of its excellent properties (i.e., high strength, toughness, and corrosion resistance). [1][2][3][4][5] It can also be used as structural steel for railways, vehicles, bridges, and towers and can withstand long-term atmospheric exposure. 6 In the future, an increasing amount of WS will be used in low-temperature environments (below the scope of the usual test temperature of the weather-resistant welding material, i.e., below -5°C).…”

In this study the Mn content fluctuations in the deposited metals and their influence on the impact toughness and corrosion resistance were investigated. The experimental results indicated that the deposited metal containing 1.05 w/%Mn when compared with the deposited metal containing 1.34 w/%Mn increased the impact toughness by 40 % and that the increment in energy absorbed by the crack propagation accounted for 88 % of the increment in impact energy. Further, the self-corrosion potential difference between the deposited metals and the weathering steel was less than 20 mV, leading to similar corrosion resistances. The results revealed that the Mn content fluctuations did not significantly influence the self-corrosion potential of the deposited metals; furthermore, the increase in the impact toughness can be attributed to: a) the decrease in the volume fraction of the grain-boundary ferrite and ferrite side plates in the columnar zone, b) an increase in the number of large grain boundaries in the fine-grain reheating zone, and c) the refining of the martensite-austenite constituents.
