Has anyone experienced a coloration between this and improper heat treat? I am a quality/process engineer running a passivation line for medical devices. If we get product (17-4 H900) back from our heat treat vendor that is slightly discolored, and we don’t properly finish it thru polishing or bead blasting, we get dark grey or black discoloration. (I posted this in another forum before I found this one.)
