Aldo has posted on BF that he may be bringing in two new steels. the first in 1.2842 or 90MnCrV8 or O2
Typical analysis:
Carbon 0.90% Manganese 1.90%
Chromium 0.50% Silicon 0.35%
Vanadium 0.15%
heat treat for this one seems pretty straight forward, heat to 1500F, short soak, oil quench. hardness after temper similar to O1. here is link to CCT and temper guide http://www.ozct.com.tr/en/pdf/1.2842%2090MnCrV8.pdf
the second is where I have questions. C125W is proposed as an alternative to Hitachi blue/white which Hitachi won't export. with high carbon and little else, is this steel water/brine quench? still looking, can't find a cct or ttt for this alloy.
1.1563(C125W) - 1.20 - 1.35% C, 0.10-0.30% Si, 0.10-0.25% Mn
