What are the Main Characteristics and Benefits of Weathering or Corten Steels?

 Corten Steel means that due to their chemical compositions COR-TEN A and COR-TEN B steels, when utilised unprotected, exhibits increased resistance to atmospheric corrosion compared to unalloyed steels.

The corrosion retarding effect of the protective layer is produced by the nature of its structure components and the particular distribution and concentration of alloying elements in it. The layer protecting the surface develops and regenerates continuously.

Chemical Composition of Weathering Steel (heat analysis, %)

Grade	C	Si	Mn	P	S	Cr	Cu	V	Ni
COR-TEN A	≤0.12	0.25-0.75	0.20-0.50	0.07-0.15	≤0.030	0.50-1.25	0.25-0.55		≤0.65
COR-TEN B	≤0.16	0.30-0.50	0.80-1.25	≤0.030	0.030	0.40-0.65	0.25-0.40	0.02-0.10	≤0.40

Applications of Weathering and Corten Steels

Weathering and corten steelis used for various types of welded, bolted and riveted constructions e.g. steel frame structures, bridges, tanks and containers, exhaust systems, vehicles and equipment constructions.
