Descaling of Cobalt-Chromium Alloy (L-605)

I am working in medical device manufacturing company. I want to remove scale/oxides from laser-cut cobalt-chromium (L-605) parts. What should be the acid-pickling solution for cobalt-chromium? I have tried with concentrated nitric acid at 80 C, but not get effective results. can ultrasonic generator be used for this purpose?

You can remove scale by shot blasting or shot peening
