northbayforge Posted July 16, 2011 Share Posted July 16, 2011 Anyone have experience forging corten (same as A588). I'm afraid it might be very tough and slow moving compared to mild steel. Thanks, Jim Quote Link to comment Share on other sites More sharing options...

bigfootnampa Posted July 16, 2011 Share Posted July 16, 2011 I've no experience with it but I would expect that you'll see little difference between Cor-Ten and mild steel. Carbon levels are similar and the alloy percentages in Cor-Ten are pretty small. It appears to me to also have quite minimal weathering advantages... minimal payback for the sharply increased costs (IMO). Quote Link to comment Share on other sites More sharing options...

Sask Mark Posted July 17, 2011 Share Posted July 17, 2011 David Brown did some elaborate gates with Cor Ten. Quote Link to comment Share on other sites More sharing options...
northbayforge Posted July 17, 2011 Author Share Posted July 17, 2011 Beth, Corten is supposed to weather very evenly, I'm thinking a good choice for an exterior project, near salt water. My community needs the entrance to our cemetery completed, possibly with an arch. I'm hesitant to use mild steel because with the high percentage of carbon nowadays, it weathers so badly. I'm considering stainless steel or silicon bronze boat shafts, though I really don't know much about those materials either... JIm Quote Link to comment Share on other sites More sharing options...
bigfootnampa Posted July 17, 2011 Share Posted July 17, 2011 Well salt water is a killer for Cor-Ten! It's protective weather film only forms under a very narrow set of environmental conditions. Users are often surprised to find that it rusts away even faster than unprotected mild steel under many conditions. Considering the price differential this must be a very distressing discovery! Paint, for example, can lead to frighteningly quick rust through areas. Salt water environments likewise. Do some reading about the actual performance of this product before buying it! IMO it is a smoke and mirrors product with a non-performing record and a HUGELY inflated price. This Wikipedia article has several interesting examples to consider.weathering steel (Cor-Ten) Quote Link to comment Share on other sites More sharing options...
northbayforge Posted July 17, 2011 Author Share Posted July 17, 2011 Bigfootnampa, Many thanks for the heads up, cautioning about corten. I think I'm going to be looking for a bunch of boat shafts for this project. Jim Quote Link to comment Share on other sites More sharing options...
bigfootnampa Posted July 17, 2011 Share Posted July 17, 2011 You are welcome Jim! I just hate to see a product sold at kind of highway robbery prices that then fails to perform anywhere near as advertised! Sort of a fake product... really just a scam (IMO).

BIGGUNDOCTOR Posted July 18, 2011 Share Posted July 18, 2011 Sea-Land, Conex, storage containers, whatever you want to call them are made of CorTen. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted July 18, 2011 Share Posted July 18, 2011 Cor-ten also stains any concrete or paving stones under it very badly with rust. There is a building at Cornell University that was sheathed in cor-ten and the sidewalks looked awful around it. Can you get the boat shafts donated for the project? Make a big difference in price!
