TRITANIUM Maxalloy stick electrodes

admin

Ok, I've gotta put this one out there.  A student of mine brought me a box of Kimball Midwest private branded "tritanium Maxalloy" electrodes.  their website doesn't have much info other than they boast a 128kpsi tensile strength and that they are good for "Universal mild steel" application.has anyone used these before?  Are they worth hanging onto? should I toss the box at my group of ravenous rod-burning welders to be?thanks!Teach Ag Mech - Mike At Home:Lincoln Electric AC225Miller Challenger 172Gas AxeWork:eclectic bunch of 90's vintage blue boxes

Reply:Well one thing you might consider doing is to try some destructive testing with them. If they are of the higher tensile that your research indicates and you weld up some A36 and do a face bend you will see the base metal pull away from the weld metal, not as in physically separating, but more so in seeing the weld metal standing up from the base metal due to the base being softer and the weld metal being harder. Right along side of this have a similar set of bend straps welded with E7018 and maybe one more welded with E6013. When you are done you should see some marked differences between the weld metal reaction to the base metal with each of the examples providing that they don't have any discontinuities or cracks. A groove weld with a backing on some 3/8" plate should work well for this demonstration with some 2" straps cut from them and face bends tested.  Back to the Kimball, if memory serves me correctly they are a manufacturer similar to Bohler, Eutectic, and a number of other "high end" specialty rod manufacturers. One thing that comes to mind is "Eutectic 680", it is somewhat of a "wonder" rod that is produced by Eutectic and can be used for joining many different grades of steels to their likeness or dissimilar's. If you don't have any real purpose for it and if you don't decide to attempt to sell it to someone that can use it for it's intended purpose, I would say, let the students play and you play some too. Good luck and best regards, Allanaevald

Reply:ok, to clear things up a little, I called kimball to get a price for the donation reciept.  The stuff is $10/lb!! looks kinda funny to be a $100 bill, not to mention it doesn't fit in your wallet quite the same wayTeach Ag Mech - Mike At Home:Lincoln Electric AC225Miller Challenger 172Gas AxeWork:eclectic bunch of 90's vintage blue boxes
Reply:Originally Posted by teachagmechyou seem really interested in them.  I'm not at liberty to sell them as they don't belong to me specifically, but i'd like to know why you want them so bad.  I've heard of the eutectic rods and other high nickel wonder alloy rods, and even have a few random wonder electrodes laying around, just wasn't sure if they were made with snake oil or just the tears of a thousand door-to-door salesmen
Reply:I would guess they are 312 stainless type rods, similar to all the other rods with odd names to try and justify the cost, like Super Missile Weld, etc. The only puzzling thing is you say "Universal mild steel" electrodes. 312 stainless are used for tool steel, spring steel or any type of steel you're not sure what it is in addition to mild steel. However, if you knew you had mild steel, why waste so much money on specialty rods that aren't required???Last edited by Welder Dave; 02-06-2015 at 07:09 PM.
Reply:^^^^ he didn't waste $$ a student brought them in to school
Reply:They weld like bad 6013 or 7024. They will weld uphill but not very well. The slag "coagulates at the top of the puddle and makes a mess.

Reply:Well then why waste them on mild steel if you can save them for when you have a tough job?
Reply:these rods sound like undercover stainless electrodes. that could explain the claims of elevated tensile strength.i.u.o.e. # 15queens, ny and sunny fla
Reply:Hello Mike, is it possible that they are designed for straight polarity? Basing my question on the general application of reverse polarity for most DC rods. I know that you said you had found them on Kimball's site, but did they give polarity, amperage range, position, information like that? Good luck and regards, Allanaevald
Reply:I'll have to look at the box again when I get back on Monday. It may want straight polarity but they ran like a wet dream downhill. Sent from my dumb smartphoneTeach Ag Mech - Mike At Home:Lincoln Electric AC225Miller Challenger 172Gas AxeWork:eclectic bunch of 90's vintage blue boxes

Reply:It's got a chromium and nickel warning on the box, I'm sure it's a 312-like rod. Sent from my dumb smartphoneTeach Ag Mech - Mike At Home:Lincoln Electric AC225Miller Challenger 172Gas AxeWork:eclectic bunch of 90's vintage blue boxes
Reply:I very much doubt it. It doesn't have any of the key features of 312.The "Ultralloy" listed above it is probably very similar to 312 stainless because it specifies it's crack resistant and can be used on tool steels, and has very high tensile.All stainless fillers have Ni and Cr, and I think most non-stainless fillers have a little bit of it too...Last edited by MikeGyver; 02-06-2015 at 08:48 PM.Welding/Fab Pics: www.UtahWeld.com
Reply:If it's 312, it won't stick to a magnet. Also they would charge a lot more than $10/lb. for it- that's about what no-name 312 rods go for. If it does stick to a magnet, it's probably a general-purpose "maintenance" rod like all those companies sell.JohnA few weldersA lot of hammersA whole lot of C-clamps
