Corten steel

Try respelling as "Corten" steel, and search again. It is one of the higher-tensile steels, if I recall correctly.

Yes it is true, it is "Corten" steel and is very high Tensile Steel, but i need Chemical Composition for the same.

http://en.wikipedia.org/wiki/Weathering_steel

Going entirely from my suspect memory, I believe it is essentially mild steel with about 5% copper.

This makes it easy to weld, increases tensile strength significantly and it forms an impermeable, protective oxide coating which makes it corrosion resistant.

The corrosion resistant coating is interesting because it takes a bit of time to develop and can lead to water run-off rust stains on concrete etc below it.

Apparently it can be left unpainted in normal exposure situations, but needs further protection for marine exposure or heavy exposure to acid industrial pollution.

Haven't seen it used for years.

Oops! sorry, should have been 0.5% Cu, not 5%.

Thank you for the help, but both the pages are unavailable.

By googling "corten steel properties" this is the first or second item that came up:
