As you posted the question over a half year ago, I hope/expect that you've found an answer from another venue.
AMSQQC320 [link by ed. to spec at TechStreet] can be called out with two modifiers. Class and Type. Class 1 is decorative and/or corrosion protective. It has a thickness of .00001". Class 2 is an engineering plating and needs to have thickness and hardness called out. Type I is bright finish and Type II is satin.
