Stainless Blades
Stainless Blades
(OP)
All,
I am looking for a Series of Stainless that will take and hold a cutting edge on material of about 0.01" - 0.017" of thickness. It will be coated with an anti-stick material after grinding the edge. Also any recommendations on what type of grinding would be best. Chemical vs. Mechanical?
Regards,
Rich.....

RE: Stainless Blades
As to grinding you can go either direction depending on the precision need, though both are very precise.
We used a twin disk machine to produce a sharp edge on a metal band blanks. To produce ultra precision edges we use a machine like a mechanical lap with different abrasive plates.
A material, not a SS but very tough, now being use on very small mechanical cutters on medical devices is Carpenter Aermet 100 produced by the Special Products Division of Carpenter in San Diego, California.
Checkout the following.

440C Strip I would also look at 440C Modified, I have some data showing this material is considerably better that 440C currently used on a little heavier cutter than your requirements.

Here are three companies that I have worked with in providing blades.

RE: Stainless Blades
nornrich in addition to the information supplied by unclesyd. I strongly suggest you look at the Kolsterising process or one of its clones. Choose 316L or a duplex type stainless, but preferably a ss with plenty of chrome, and Mo. The process allows carbon to form carbide compounds with Fe and is discouraged to combine with Cr. Traditional hardening methods permit carbon to combine with Cr and render the metal no longer stainless. What you end up with is a seriously corrosion resistant ss with a 70+ Rockwell 'C' scale surface to a depth of 30 microns.
Downside: Use and when worn, throw away.
Fortune favours the bold and avoids the unprepared.

Corrosion, every where, all the time.
Manage it or it will manage you.

RE: Stainless Blades
As I was about to post a reply, it was suggested by the other Forum owner that Richard post in another Forum and instead of a reply I suggested a couple of possibilities and he availed himself of this particular Forum to post his query. That is the reason for the double post.
