What color or tint should I expect to see after 17-4ph stainless has been hardened to condition H1075?

I had an accurate part machined to 0.01 mm tolerance. After passivation the dimensions were lower by 0.05 mm thereby rendering the parts useless. Therefore, if your part dimensions are accurate beware that passivation process of heat treated parts with heat tint (even after vacuum process) can make your parts useless.
The correct way is to final machine all accurate dimensions after heat treatment. All non critical dimensions should be cleaned by mechanical means such as aluminum oxide fine grit blasting. The idea is to bring all final part to the passivation process without any heat tint no matter how thin it.
