Corten B steel sheet is a kind of weather resistant steel, which is better suited for heavy and load bearing structures. Corten B sheet is produced from billet castings from blast furnace and hot rolled in a continuous mill for smaller thicknesses and on a four high mill for others. The purity of the steel of fine grade austenitic quality and the addition of special alloys, provide this steel plates, excellent mechanical characteristics, even at high temperatures and self-passivating properties when exposed to corrosive agents present in urban atmosphere. This property allows this steel to face down corrosion for longer periods when compared to common steel, even if not painted.

ASTM Corten B Application
The mechanical characteristics and the resistance to atmospheric corrosion make this steel, the best product for the fabrication of agricultural vans and railway wagons, structures of bridges, water pipes, fans, chimneysand boilers.
The material forms its own protective layer when exposed to atmospheric elements. Essentially, the top layer corrodes and 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.
Mainly used for construction of tanks, containers, bridges, frame structures, vehicles, etc with the request of welded, bolted, etc.
ASTM Corten B Service
These Corten B plates are in a variety of sizes and thicknesses, and is available as ex–stock or directly shipped from the mill. As with all our steels, our plates come with mill test certification, stampings and fully traceable. We can arrange for a variety of tests to be performed on the material if specified.
