Cor-Ten®
A
The original Cor-Ten® A
alloy has a yield strength of 50,00r
0 pounds per square inch (340,000 kPa)
and ultimate tensile strength of 70,000 psi (480,000 kPa) for light-medium
rolled shapes and plates up to 0.75 inches (19 mm) thick. It has yield
strength of 46,000 psi (320,000 kPa) and ultimate strength of 67,000 psi
(460,000 kPa) for medium weight rolled shapes and plates from 0.75–1 inch
(19–25 mm) thick. The thickest rolled sections and plates – from 1.5–4 in
(38–102 mm) thick have yield strength of 42,000 psi (290,000 kPa) and
ultimate strength of 63,000 psi (430,000 kPa).
Cor-Ten®
B
Cor-Ten® B has a yield
strength of at least 50,000 psi (340,000 kPa), and ultimate tensile
strength of 70,000 psi (480,000 kPa) for all rolled shapes and plate
thicknesses up to 4 in (100 mm) thick. Plates from 4–5 in (102–127 mm)
have yield strength at least 46,000 psi (320,000 kPa) and ultimate tensile
strength at least 67,000 psi (460,000 kPa), and plates from 5–8 in
(127–203 mm) thick have yield strength at least 42,000 psi (290,000 kPa)
and ultimate tensile strength at least 63,000 psi (430,000 kPa).
