I was looking at some data sheets for 6011 and 7018 to compare the relative strength of each electrode. I was surprised to see how strong Hobart 6011 type 335C is. I researched this for a different subject about tack welding with 7018. They make several variations of each type. Each one has different properties which makes electrode selection very confusing. Lincoln has even more types of 6010 and 7018.
The Hobart 6011 type 335C has 94,000 psi tinsel strength and 85,000 yield strength.
So why do they call it 6011 instead of 8011 or 9011?
I know a lot of these modern electrodes far exceed their minimum listed ratings. People say 6011 or 6010 is weak. If you burn in a weld and use proper technique your weld will be stronger than most parent metals.
