| Does anyone know anything about Corten Steel? It is sheet metal with high tensile strength and it will not rust, only oxidize. |

Corten
I know enough to be dangerous. I believe U.S. Steel makes it, I don’t know if anyone else does. It can have structural applications, I’ve seen it used on electrical power poles and structural building columns that were left exposed. I’ve seen it used mainly as an exterior cladding material. The one I am most familiar with is down in Austin at UT. It was built some time in the early 70’s. There are some problems with the material from an architectural stand point, it is easily discolored by anything that rubs against it. The building at UT originally had siding from top to bottom (3 or 4 stories), soon after it was built they came back an added masonry to the first floor to stop graffiti problems. There are exposed corten columns on a local elementary school and we have never seen any discoloration problems on them. I have noticed that in time its color continues to get darker. I have not actually worked with it myself.

Rand Does it look rusty at all as it ages? I read somewhere that it turns to a purple color? Welcome to the shop! |

When corten is newer it has more of an orange tint. The columns here in town are thirty years old and they are dark dark brown with a slight purple tint. You might find pictures on an architectural publication web site; like architectural record.

I believe it's Cor-Ten,a brand name for corrosion resistant products developed by U.S.S.
Like untreated copper it developes a protective oxide film which slows further corrosion.
Looked at a picture of a 40 yr. old bldg.Sort of a orange/brown color...Try Google/type in:
define Cor-Ten

| Cor-ten is a high strength low alloy steel or HSLA. Its yield is about 50,000 psi versus somewhere around the mid 30's for normal sheet. If you're looking at fabbing something from it, its not hard to form and works about like regular hot rolled. Would take a little bit more power for bending, rolling, etc but not a lot more. Whether it could be run thru something like a pittsburg without cracking......don't know about that, and don't really know how thin its currently being rolled. It's available up thru 6" plate. I've made parts from it for GE's turbine division where they use Cor-ten for all their field mounting and leveling plates and brackets when they install these turbines. I've bought Cor-ten plate from Central Steel in Pelham Alabama and they have a good stock of it. If you were looking for sheet thickness material, if they don't keep it I'm sure they could direct you to someone who does stock it. The generic spec for cor-ten and similar products by other makers is ASTM A-588. |

 Cor-Ten is has not been well received by the boat building community because it is too heavy and does not really hold up well in the marine environment. |

| Used corten quite a lot a few years ago building large metal plynths for bronze sculptures to sit on ,the only problem apart from the cost was that the patination on the steel would run staining the concrete under them .But anything that you can do to mild steel is doable to corten .aw ra best Marky |
