Yep, Bob I am aware of that. It's generally a test whether the part 'leaps' to the magnet(regular steel) or just barely hangs on. I'm normally using a rare earth magnet from a dead 'puter hard drive when I do my 'testing' so they are strong. Most 316 SS washers (from McMaster Carr McMaster-Carr
) I've been using are slightly magnetic. I have some general use tie wire that's that way as well.
