This is my first post on the forums, but I have been lurking for a while reading articles and absorbing information. I am an electrician and since starting to fool around with blacksmithing after taking a few courses at new England school of blacksmithing I have been waiting for scrap to fall my way at work. So last Friday we were cleaning off the last job and the general contractor said I could have at the metal that the welders left because they said they weren't coming back for it. It was about 100 ft of 5/8" steel rod. I would assume if they are welding it, and it rusted that it would be safe for the forge, but being a little new at this I figured couldn't hurt to just ask. And this question is also a good chance for me to finally join the discussion of the forums instead of just lurking and reading. I have read the forums on what not to forge and such, but I suppose it is just me being cautious as this would be the first thing I stick in the forge that I didn't buy from the supply yard. Thanks in advance for any and all advice.
