I have 12 pcs to quote. The parts are about 300#'s of 4340HT, and need repairs to the bottom surface of the counterbores.
The Ø2.5" bolts that held the piece down for 10 years, were rusted to the main part.
The end user used either an Oxyacetylene torch, or an oxy lance to remove the bolt heads.
They unfortunately gouged (severely) the bottom surface of the counterbore.
So, the actual question:
Will the base material be much harder, since the base material was taken above critical, and instantly cooled by the surrounding material?
Or is there a way to predict the machinability of the part, for a quote's sake?
My first thought was to price it high enough, that there would be plenty of compensated "trial & error" time.
Thanks,
Doug.
