Will powder coat baking soften 4130?
(OP)
I have some parts made of normalized 4130 steel that I would like to have powder coated. The bake cyle is 425 deg F for 8 minutes, then 350 deg F for 15 minutes. Will this amount of heating have any tendancy to soften the steel?

You will only soften 4130 if you heat the material above the tempering temperature used for the heat treatment.
