I used previously 18-8 extra thick washers without a problem. Is 304 a more brittle metal? Some sites say 18-8 is 304. I want to make sure the strength is the same as I used previously before I order them. Thanks
18-8 and 304 are basically the same and for the average person it may not matter that much.
18-8 Stainless steel has APPROXIMATELY (not exactly) 18% chromium and 8% nickel. In my experiences with manufacturers, if they are allowed to be off the 18-8 mixture, they take full advantage of that and try to put as little of the chromium and nickel in their products as possible as long as they can still classify it as "18-8".
304 Stainless steel has a MINIMUM amount of 18% chromium and 8% nickel, COMBINED with a MAXIMUM of 0.08% carbon. In my experience in the food industry, where I get to see 18-8 vs 304 washers in harsh chemical washdown environments, I definitely notice a difference. I have noticed the 18-8 will corrode much more than the 304 Alloy.
