    Hobart 6011 with 94,000 psi tinsel and 85,000 yield strength. Why call it 6011?

    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.

    cause welder looking for 6011 rod, if it was labeled 8011 fewer would buy it. those tensile strengths are not guaranteed. it is like internet speeds they say 12 mbs but normal might be 8 mbs............ so you got max number and minimum number. with 6011 then 60,000 tensile strength is minimum rating and higher strength is normal but not guaranteed

    I would market it like high performance ammo +p+. The 6010 5p+ is a lot different than normal 6010. I know a lot of electrodes exceed the nominal ratings by 5-10,000 psi but 25-34,000 psi strength above the nominal rating is exceptional. I wonder if they are giving BS numbers. I don't think Hobart would overstate the performance that much.

    I couldn't find that specific type it just listed Hobart 6011. Any suggestions where I could buy a 50 lb can of 1/8" Hobart 6011 335C?

    They sell a different version. It's Hobart 6011 770457

    Not all Hobart 6011 is the same. This 335C version of 6011 is 50% stronger.

    I found the data sheet numbers on this site. I may have to order the directly from Hobart tho get these specific rods.

    The Hobart 6011 335A has 82,00 psi tinsel and 69,000 yield strength. Not nearly as strong. I think the bulk stuff for Tractor Supply is even lower strength.

    6011 is AWS designation so the question is how does AWS classify rods. I have an old Hobart catalog. Both rods listed 335A (AC only)and 335C have tension strength greater than 60,000, yet are specd by AWS as 60k.

    It looks like Hobart improved their 6011 335C a lot since you bought yours. Or they are seriously BS-ing everyone. The new version has 9 trace elements and most of the other elements are similar quantities.

    The Hobart 335C is a good rod designed to run on low voltage AC welders. Runs very smooth on DC machines too. It may have a 94K tensile rating, but that is ultimate strength, doesn't account for elongation before failure, etc. Meaning don't use the stuff in highly stressed applications. That is what 7018 type rods are for. "Toughness" VS ultimate tensile strength is hard to explain. 7018 will stretch, 6011 won't. That's the best explanation I can give. Others will be along shortly.

    It has 26% elongation. Does that mean it can stretch as much as 26% before the weld fail? So it could not bass a bend test where the weld is bent in a U shape. I only use it for rusty old trucks, trailers, and machinery.

    The elongation is after a specimen fractures in a tensile strength test . I suppose it can also be measures as it is being stressed, but you still have to get it to fracture to see how much elongation you get.

    High elongation numbers = "more ductile" = "tougher" = it'll bend/stretch/elongate/twist/upset more before it fails.

    Think 7018

    I believe the technical answer is:

    It's more betterer.
