Low tensile pipe, low tensile electrode? I dunno.. I have even field repaired some hyd piping on a excavator boom and the 6013 held, the previous shop repair with 7018 failed. Like I said, I can't explain it or condone others doing it out of legal reasons. But for me it worked when nothing else did........
Heck, I made some redneck quickie tractor bucket forks with 6013. 
No weld cracking issues - but I did eventually bend them into a pretzel, straighten and bend 2 more times.
