I got a large (approx 17"x2"x0.5") piece of mystery tool steel from an industrial liquidation store (npsstore.com) in my area a few weeks ago. My brother took it to his work where they have a Positive Material Identification tool to read the actual composition. But I'm having trouble making sense of it in terms of identifying the actual alloy so I can find the appropriate application and heat treat info.
Because it is clearly a guillotine type blade I was expecting an A-series alloy, such as A2. But there's no manganese and chromium is too high, so it's not an A-series alloy. The display says "TS-D2/3/4" at the top. Not sure what that was, so I thought maybe it's saying, "Maybe a D-series alloy??" And that seems closer, but still not quite right, according to the charts I'm looking at.
And the readout doesn't even show Carbon composition. That seems weird. Anyway, here's the text from the scan:
Typing this on the computer. Image is on my phone, so I'll add it in the first comment. I asked my brother for more info about the tool and so forth (like a model number so I can look up the manual...), but I figure even if he comes back with precisely what I'm looking for this might still be an interesting exercise for the friendly folks of this forum.
