i have a large amount of black steel pipe which was pulled out of a basement from old boiler lines. i am wondering if this is any good for blacksmithing projects, i am guessing it is some form of mild steel?
I also have a big pile of old lawnmower blades I saved from a junk pile. Just wondering if anyone knows specific types of steel usually used on these items and what types of projects, if any, they might work for.
thanks
