Corten A Steel Tensile Requirement

Corten A steel plate and strip is also known as weathering steel that is instantly identifiable due to its rich and bright orange tones. CortenA plates and strips are produced 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.

Corten A Steel Tensile Requirement

The mechanical properties of Corten A are outlined in the following table.

Grade	Thickness (mm) Strip Products	Plate Products	Yield Strength Rel N/mm² Minimum	Tensile Strength Rm N/mm² Minimum	Elongation A50 % Minimum
Corten A	2 – 12	6 – 12	345	485	20

Corten A Steel Strips Element (% max.)

Grade	C	Si	Mn	P	S	Cu	Ni	Cr
Corten-A	0.12	0.25-0.75	0.20-0.50	0.07-0.15	0.03	0.25-0.55	0.65	0.50-1.25

According to the performance and the requirements from clients, the status on delivery of Corten A steel plates can be hot rolled, controlled rolling, normalizing, annealed tempering, normalizing + tempering, hardening + tempering, etc.
