ASTM Corten-B steel is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance.
Description:ASTM Corten-B steel is according to ASTM standard which with the yield strength of 355MPa and 345MPa which is based on the different thickness.The anti-corrosive properties of Corten B steel are better than those of other structural steels in many applications. Corten B steel is self-protecting. The rust layer on the surface becomes a tight oxide layer that slows down the progress of corrosion. Corten B steel is an economical, long-lasting and fully recyclable material.
Application:ASTM Corten-B steel is used for various types of welded, bolted and riveted constructions e.g. steel frame structures, building cladding, metal sculptures (Angel of the North), chimneys, bridges, tanks and containers, exhaust systems, vehicles and equipment constructions. As it ages it takes on a orange/brown appearance dependent on the salt level of the atmosphere, over time it forms a protective layer or skin against the elements. It was originally developed to eliminate the requirement of painting surface finishes. In most circumstances, Corten-B steel plate and sheet for steel atmospheric corrosion resistance is better than carbon structural steel plate and sheet containing copper or not in essence. When fully exposed to the atmosphere, Corten B can be widely used in many cases under bare (uncoated) condition.
