I have some plungers made of 38CrNiMoAlA. Their required hardness to be achieved via quenching/tempering is 51 HRC. I've scoured our technical order for heat treatment of steel alloys but the material is not there. I even checked the internet, it doesn't seem to exist at all. The closest I could get was 38CrMoAlA. Please help if you know this material or something close to it.
My google search turned up nothing..
