are black steel weld els the same as mild steel
exactly what the title says, no one around my area sells "mild steel weld els", but at home depot i found "black steel" elbows that look exactly the same. the guy told me that the black is just a paint that they put on there to keep it from rusting and that the metal was cold rolled mild steel.
any one ever try these or should i just buy some from acestainless

HD ---- is just cast steel, if not cast iron. Its not so much paint, its an light anti-rust coating.
I can say it welds nicely, I made a mani from their 2" black pipe and elbows, and with my awsome MIG'ing skillz its still holding the T3 turbo in its topmount config 8 months later. No cracks anywhere. Can't beat a $7 manifold :1

Re: are black steel weld els the same as mild steel
well i can say that those elbows sucked ***, i started by cleaning them off and then putting some sopt welds around where i was welding and as the were cooling they just cracked right in half. at first i was using 100amps but that wasnt getting the job done so i upped it to about 175 and fused away, i got nice penetration all the way through but as soon as i let the whole thing cool it just cracked right down the center of the weld and was easily broken apart.
