Oil quenching 17-4 PH
Oil quenching 17-4 PH
(OP)
Has anyone heard of an H900 process on 17-4 PH that involves oil quenching? Possible in europe?
Thanks!
Thanks!

I love materials science!

Thanks for the response. I have never heard of oil quenching of PH steels and couldn't figure out why you would want to do it.
Someone new to my organization (not sure might be my boss some day) insists that he worked somewhere that did oil quenching. I'm just trying to:
a. figure out why
b. figure out if he knows what he is talking about.
Thanks,

With very large sections, there may be concern that air cooling from the solution treatment temperatures may not be rapid enough to prevent transformaton. I am not sure how large the section has to be for this concern to be valid, however. I know that air cooling is fine for solids up to 6 inch (150mm). I think it is more important that to cool it below 100 deg F.
I cannot remember the specifics, but I do seem to remember some specifications in the mid 1980's that called for air cooling or oil quenching from the solution treatment temperatures for 17-4.
