Core 10?

I have a customer that has requested some materials to be fabricated from 1/4" "Core 10" metal. Could you please tell me the difference between "Core 10" and regular carbon steel? I have asked our steel suppliers, but the only thing they can tell me is that it cost more.

Thank You, Sincerely,

Well, there's Cor-Ten steel, a product of US Steel. It's a carbon sheet steel with copper added, and when rusted the oxide layer becomes sufficiently thick that it prevents further rusting. See US Steel's web page on the stuff at http://www.usx.com/corp/Plate/products/usscortn.htm.

I'd guess that this is what your customer wants. You may want to verify.

Good luck!

The name is COR-TEN and it is a trademark of US Steel for their grades of weathering steels. Weathering steels possess enhanced atmospheric corrosion resistance, as well as high strength and weldability.
