Looking for cryo treatment parameters of a rather uncommon steel?!?
Hi!
I need your help regarding cryo treatment parameters for a steel called CRV2/1.2631. As I want to get the finest possible grain, I want a cryo treatment having done with it as a part of the heat treatment. The metallurgy of the steel reads C - 0.5% Si - 0.9% Mn - 0.5% Cr - 8.5% Mo - 1.2% W - 1.2% Fe - balance I want a cryo treatment right after hardening/quenching prior to a double or triple temper. Information on the standard heat treatment can be downloaded here: PDF file. Any recommendations? Thanks for your help!!! Best Regards Mark23 |

Here is an other Link with information on the heat treat cycle with a triple temper PDF file.
By the way, which parameters would you choose to get the finest grain out of this steel? The tungsten should eat up quite a lot of the carbon when doing a high temperature tempering (aiming for secondary hardness), and the tungsten carbides should be very small ... Additional info on the geometry: The knife has a length of about 220 mm and is ground from 1/8 stock. Thanks!!! Best regards Mark23 |
