    Default 306 stick electrode?

    I have several pounds of 3/32 rods that I got awhile ago unboxed. The only markings I see on them is 306. They are a light in color, almost white, with a green overcoat that is very lightly & unevenly applied. Kinda like sponged on if that makes sense. There is no rust or corrosion on the stinger end. I assume stainless but can't find any info anywhere. My Hobart book shows 308 as the lowest ss stick rod. Anybody have a clue as to what they are?

    Looks like it is an aircraft quality stainless, i have never used it before but it can be welded by all the regular welding processes except for oxy fuel

    After some more searching I found a hard facing electrode "Stellite 306". I still don't know for sure so I guess they'll just sit on the shelf some more.

    edit- the above stellite 306 are only tig rods.

    That seems to be the closest I've found. Thanks for finding it. Upon further looking the stellite rod I found is only a tig rod. I'll have to try these out on something that isn't critical.
