ASTM Corten steel plate

CORTEN steel plate introduction: ASTM Corten steel plate is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance.The steel grade Corten A is according to ASTM standard which with the yield strength of 355MPa and the tensile strength of 470-630MPa. Corten-A steel was first used in buildings in 1958 because it has anti-corrosion properties. Then Corten-A especially in China and Japan was widely used for bridges, trains, cars, trucks and industrial facilities and so on. Grade Corten B steel is according to ASTM standard which with the yield strength of 355MPa and 345MPa which is based on the different thickness.

Application

CORTEN steel plate application:
Corten steel plate is also called a weather resistant steel which is better suited for heavy and load bearing structures. The material forms its own protective layer when exposed to atmospheric elements. Essentially, the top layer corrodes which then protects the steel beneath it. The natural finish does not normally require any form of maintenance such as painting, which makes the material a highly cost effective alternative to other structural steels.
