dimensions changing after hardening

[leewald]

I am in the process of machining bushings for heavy machinery. If the final dimensions of the bushing are: OD 3.55", ID 2.5" and 1.9" long, how much of a dimension change can I expect after hardening. The material being used is alloy steel, 8620. Thanks

Are you intending to carburize these parts or simply quench and temper?

Just quench and temper.
