B550NQR1 Weathering steel plate, B550NQR1 steel sheet Non-secondary

B550NQR1 Weathering steel plate, can be achieved by the addition of copper and phosphorus has been significantly improved, and to improve the effectiveness of the most significant Canadian copper. Excellent weather resistance is due to the B550NQR1 steel surface to form a dense layer of rust, the steel substrate and the air of isolation and effectively stop the rust continues to grow.

B550NQR1 steel sheet has been widely used in the manufacture of containers, rolling stock, oil derrick, harbor construction, oil platforms and oil equipment chemical structure containing hydrogen sulfide and other corrosive media container. B550NQR1 steel plate can also used to building structures, vehicles, bridges, railings and the like atmospheric corrosion resistance is required field.
