How does 304L compare to 303S on the basis of corrosion resistance and machinability? Also experimenting with 316L; but cost concerns and machinability point to 304L. Any help in this manner would be very much appreciated. (303S is what we currently use, but would like to use a metal that does not need to be plated in order to reach desired corrosion resistance).

303S vs 304L

The 303S is considered a "free machining" stainless. It has a machinability factor that is better than 304L or 316L. However, you will sacrifice corrosion resistance with this material. I recommend going with the 316L. You can spend a little extra on the material and buy from Carpenter. Their material is manufactured using a more refined process than some other commodity steel manufacturers. What you lose in the extra material cost will easily be made back up with less tool wear and downtime.
Good luck!
