Stainless steel finish and the weather/elements

[fritter63]

So, been thinking about the CT "finish"...

Attached is a picture of my relatively new Webber grill, in SS. It's been out in the (mild!) winter here in California (we are way down on rainfall totals this year) and I forgot to recover it a couple times for rain storms. Not sure the picture does it justice, but it gets this kind of "scaling" on it. You can wash most of it off but have to actually polish it (with SS polish) to get rid of it.

What am I missing? Will this not happen to the CT? Or is it a different kind of stainless?

It depends. Grills are often 304 or less expensive 430. If a magnet sticks to yours its 430 ( corrodes easier) and we know that CT will be 30x

The black magnetic SORT OF stuck, slid down to the edge.

Neodymium nothing at all.

Looks like it is likely 430 though.

But that doesn't jive with my magnet test.

Very interesting article.
