    Addendum: Doing some online research, I find the interesting detail that Pandrol e-clips are available in four different alloys:

    1. 60Si2MnA (C:0.56-0.64, Mn:0.60-0.90, Si:1.60-2.00, Cr:≤0.35, P:≤0.03, S:≤0.03)
    2. 60Si2CrA (C:0.56-0.64, Mn:0.40-0.70, Si:1.40-1.80,Cr:0.70-1.00 P:≤0.03, S:≤0.03)
    3. 55Si2Mn (C:0.52-0.60, Mn:0.60-0.90, Si:1.50-2.00,Cr:≤0.35  P:≤0.03, S:≤0.03)
    4. 38Si7 (C:0.35-0.42, Mn:0.50-0.80, Si:1.50-1.80, P:≤0.03, S:≤0.03)

    The first two are fairly close to 5160, I believe, although a bit low on the manganese.

    the greens are 16mm, the 18 are red. The steel in them is usually a variant of 9260; which is a great steel for tooling; mediocre for knives. Tough stuff. Doesn't want to move under the hammer. Don't forge it too high, it suffers from grain growth like O-1. Normalizing is also a good idea. Testing for cracks is also a great idea after forging. Not that great for tongs.

  3. The only way to tell for sure is to have the sample piece tested.  That will them be the test results for ONLY THAT ONE piece of steel.

    If you want a specific spec for steel, then purchase that specific specification. It should come with analysis information on heat treating etc.  That entire lot should all act the same.  If you like the way it preforms, quickly go back and purchase all you can afford of the same specification.

  4. I did a Google search for rail anchor specifications and/or rail anchor steel . Apparently the material is 60Si2MnA I have forged a few punches and cold chisels from rail anchors. After quenching and tempering to a light straw color they cut mild steel like a hot knife through butter. Dickb 1/21
