Stainless Steel Surface Quality for Ophthalmic Surgical Device

#1
Dear all,
I'm part of a group developing a device for an ophthalmic surgical procedure. The device is composed of stainless steel 420
I'm looking for relevant guiding standards providing requirements for surface quality (and additional attributes) for (such) stainless steel surgical instrumentation.

I'm already familiar with the following:

ASTM F0899-09e_Standard Specification for Wrought Stainless Steels for Surgical Instruments

Appreciate your assistance.
Many thanks,
Eyal

Hi Eyal,

420 sounds strange. Why not 316 or 304?

Cheers,
Ronen.

It's a bit difficult to give specific advise without specific details (Even if you provided specific details, its not my specialism so I'm not going to be much help); consequently, a general answer is that the requirements for your device surface qualities are those that you specify as appropriate for the intended use

You may want to consider:
1. roughness
2. carbide formation
3. contamination (physical and microbiological)
