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

Weathering 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

COR-TEN A Mechanical Properties

Grade	Minimum yield point ReH Mpa *)	Tensile strength Rm MPa	Minimum elongation A (Lo=5.65 √So) %
COR-TEN A	355	470 – 630	20

COR-TEN B Mechanical Properties

Grade	Material thickness mm	Minimum yield point ReH Mpa *)	Tensile strength Rm MPa	Minimum elongation A (Lo=5.65 √So) %
COR-TEN B	≤16	355	470-630	20
COR-TEN B	> 16 ≤50	345	470-630	20

Applications of Weathering and Corten Steels
