ATMOSPHERIC CORROSION is the degra-dation and destruction of metallic materials and their structure and properties due to interaction with the terrestrial atmosphere at its character-istic air
ASTM Weathering Steel Specifications Central Steel ServiceASTM A588 is a high strength low-alloy structural steel specification with improved atmospheric corrosion resistance for structural steel shapes such as angles, channel and beams, as well as steel plate and bars.
ultimately replaced by ASTM standard A588 WS  (see Table 1), which is roughly comparable to USS CorTen B steel. This steel possesses less resistance to atmospheric corrosion due to its lower P content, but for this same reason it has better weldability.
Atmospheric Corrosion - an overview ScienceDirect TopicsLike all other corrosion, atmospheric corrosion is an electrochemical process, which is controlled by oxidation and reduction reactions. With atmospheric corrosion, these electrochemical processes occur in a local environment that undergoes changes because of diurnal and seasonal cycles and because of the growth of surface oxide layers.
Atmospheric Corrosion Rates of Weathering - astmTo obtain long-term atmospheric corrosion data for weathering steels such as ASTM A 242 Type 1 (USS COR-TEN A) and ASTM A 588 Gr. A (USS COR-TEN B), an exposure program was initiated in which test panels were exposed for up to sixteen years at three corrosion test sites in the eastern United States. A unique feature of this program was that test panels were exposed in four different orientations
Atmospheric Corrosion Tests. For many years, different individuals and organizations have been putting specimens out in the atmosphere in all kinds of tests and shapes. For example, corrosion of aluminum or zinc specimens in ASTM B117 primarily produces soluble species such as AlCl 3 or ZnCl 2 with little corrosion product remaining on
Atmospheric corrosion data of weathering steels. A review 3 rows · Dec 01, 2013 · Extensive information on the atmospheric corrosion of weathering steel has been published in the
Comparative atmospheric corrosion of primary and cold Atmospheric corrosion tests, according to ASTM G50, have been carried out in Queensland, Australia, at three different sites representing three different environmental conditions. A range of materials including primary copper (electrosheet) and electrolytic tough pitch (traditional cold
Scope. 1.1 This guide presents two methods for estimating the atmospheric corrosion resistance of low-alloy weathering steels, such as those described in Specifications A242/A242M, A588/A588M, A606 Type 4, A709/A709M grades 50W, HPS 70W, and 100W, A852/A852M, and A871/A871M. One method gives an estimate of the long-term thickness loss of a steel at a specific site based on results of short
What Are the Effects of Corrosion? CamfilA recent atmospheric corrosion study has helped to shed more light about how airborne pollutants directly affect metals in an industrial city environment. Researchers began with the thesis that atmospheric corrosion of metals and their alloys is very common in the industrial city environment due to the high concentration of corrosive pollutants Atmospheric corrosion of ASTM A-242 and ASTM A-588 Slight differences occur in the industrial atmosphere, where ASTM A-242 presents 1013% less corrosion than ASTM A-588. (c) In the C2-C3 ISO corrosivity atmosphere both types of weathering steels are adequate for unpainted use. However are not suitable in higher ISO corrosivity atmosphere.
