Dimensional changes in Greek Ascoloy (Heat Treating)?

Dimensional changes in Greek Ascoloy (Heat Treating)?

Dimensional changes in Greek Ascoloy (Heat Treating)?

(OP)
I'm working with 2.25'' Greek Ascoloy which needs to be heat treated to 45-50 HRC. I need to know what the material will do dimensionally during heat treating. I'm wanting to establish pre-machine dimensional parameters. I would like to finish grind to drawing requirements after heat treating. Unfortunately I have never worked with this type of steel.

The fancy name for 418 martensitic stainless.
What heat treatment are you using?
I would guess that you could estimate from 410 and 420 data, but they don't have any Ni in them so it will only be approx.
Are you using a double temper?

I'm having the heat treat operation done by an outside supplier. The spec is 2759/5.
