Ok, maybe this is a no brainer for some (not me obviously), but is there a way to sift through parts and pick out the stainless pieces? My stainless button snaps somehow mixed with the household/clothing variety and I'm looking to use the stainless on the boat and I figure there must be a method...magnet? HELP!

Yup, use a magnet... If it doesn't stick (or is very weakly magnetic), it's stainless. (or maybe nickel plated brass) ;>)

Suzie,

I remember trying to find stainless button snaps and I never could locate any.

Another indicator - stainless is sort of greyish compared to aluminum, cadnium, zinc and so on.

Good luck!

In my experience, stainless should be (but isn't always) completely oblivious to a magnet. The slightest attaction says it's going to rust. I often check fasteners with a very strong magnet at our club (one that can lift a small outboard out of the drink), and usually can detect no attraction whatsoever.

A magnet might be a fine way to do it. A magnet will confuse 400 series, like 402, with steel since the 400 series are ferritic. That's just fine because 400's will rust in most difficult sitations.

A magnet will confuse 300 series, like 316, with chromed brass, but you will be able to tell the difference when the brass parts fail.

Easy. The ones that look more expensive than they should are stainless

This thread reminds me of the time someone at the marina asked how long do you let coffee perk? They looked it up on the internet and discovered some 80 plus pages of info.
