Heat treatment
(OP)
I have a question regarding heat treatment of steel casting.
Is it acceptable/ok if a 9 hrs heat treatment chart shows an interruption - lets say 10 minutes?
Thanks in advance.

Thanks all.
RE: Heat treatment
You should indicate your heat treatment temperature and the variations in your specific case...
RE: Heat treatment
I have the spec with me,which specifies the austenitizing temperature as 1550F(845C), liquid media quenched to below 500F(260C) and then tempered at 1100F(595C).
Why have you gone for such a long austenitizing cycle ( I am assuming,as you have not mentioned)?

The part is 8", which was the heat treat time came from, I think.
Yah, per the spec, it should be cooled at liquid and then have temper per the spec.
So I am going to dig up more information.
Thank you!
