Any hardware sells hundreds of items made of iron.
The only way to get rid of it is to force pure oxygen through molten steel, not fun or easy to say the least. Again this gives impure iron with 'too much' carbon. It is called pig iron because way back when this crude form of iron was cast into ingots that looked like pigs. Your on your own if you want it any more pure. If you ask me it is more trouble than it is worth.
