303 is free machining and does not work harden like other types of stainless. I would rather machine 1,000 lbs of 303 to 1 pound of 304. 304 work hardens if you look at it wrong.
...The worst sound you can hear is a "squeal" when drilling 303 !
You are absolutely right - as I said I haven't done much stainless work in many years. 304 - not 303 - is the monster for dulling drills and sometimes even breaking them. Thanks for the correction !
