Greetings!
I'm relatively new, to the community, and to blacksmithing -- so if this is a stupid question, please bear with me. :-)
I have a propane forge and am messing around, making tapers and leaves out of mild steel (new from Metal Supermarkets).
Strangely, the steel rusts suddenly as it cools -- like I get it orange-yellow hot, let it cool down, and a layer of flash rust immediately coats it.
I've not seen this happen in any of the online videos, and none of the books talk about it: the oxide scale, yes, but not brown rust.
Any thoughts/ideas? Is there something I'm doing wrong?
Thanks for any help!
-Shawn.
