Thanks for the info guys. Only have my gassforge for the HT, so that might be a problem :-)
I found a link expalining a bit more about the steel:
https://steelselector.sij.si/steels/MERILOEX.html
http://www.otaisteel.com/105wcr6-1-2419-tool-steel/
It's describes as a "Cold work tool alloy" and doesn't say anything about soaking.
It says an equivalent would be L3 steel.
