  1. I've actually been doing research since I posted that and I found this link that gives me some clues 

    https://www.911metallurgist.com/blog/grinding-balls

    They recommend that grinding rods consist of :

    Carbon .85- 1.00%
    Manganese .60 – .90
    Sulphur .05 Max.
    Phosphorous .04 Max.
    Silicon .10 Max.

    closest composition I can find on the heat treatment app is 1090

    edit: thanks Frosty! I'll do that.

  2. Hello everyone, fledgling blacksmith here. I'm lucky enough to live by both a few feldspar processing plants and a scrapyard that still let's people in to salvage. Once in a while they get these long tapered oval shaped rods anywhere from a couple feet to maybe 12-15 feet in length. The longer ones are probably 2.5 to 3.5 inches thick in the middle and taper to points. Someone told me they thought they were rods they use to crush feldspar in big tumbling mills. It seems pretty hard to a file and their use seems to say they should be made of pretty tough stuff. Anyone here encountered rods like these or care to take a guess as to what kind of steel they are?
