Chinese VG10 compared
We've been told that Winterpuddin's VG10 is Chinese equivalent steel composition where no Chinese VG10 is actually the "real" VG10 from Japan. I was curious to compare the XRF test result of Winterpuddin VG10 vs Green Thorn VG10, and the compositions seem quite different. Cannot make me believe they are both Chinese version of VG10 or did I get misinformed?

Updated with 7Cr17Mov (which I suspect winterpuddin use), 10Cr17CoMov which is Chinese version of VG10 and 9Cr18MoV requested by another member.
