The life expectancy of paint coatings on new weathering steel is at least equivalent to the life of the same coatings on ordinary structural steel. It could even be argued that the life will be longer, as the weathering steel will resist any creep of corrosion under the paint from a damaged area.
3CR12 was designed as a corrosion resisting steel and, as such, will exhibit staining when exposed to aggressive atmospheric conditions. In applications where aesthetic appearance is important, it is recommended that 3CR12 is painted, or a higher grade should be used.ustenitic stainless steel filler metals such as AWS ER 309L, 308L, or 316L should be used. In order to ensure adequate corrosion resistance in weld zones, it is necessary to remove all heat tint by pickling or by some mechanical means and passivating with a cold 10% nitric acid solution after cleaning.
