Thanks for responding.
The defects are extremely minor, But they are there none the less. I agree and disagree with you. I agree the defects are from the springs being dropped in a big box all together, but not after being wound. After they are wound, they are nano-peened, then nitrided. These defects are present after the nano peening process so the nicks I see cant be from the winding process...
