Hello,

I am a pipeline welder of 26 years. I really haven't had much to do
with stainless steel in my career. I want to buy a BBQ and have noticed
in
the past 3-5 yrs that there are some pretty nice stainless BBQ's out there
for sale by Home Depot, Price Club etc... I also was told to watch what
you
buy as some of those pretty "stainless" BBQ's eventually start to rust!
This brings about the question of good and bad quality stainless
and
knowing what to look for when buying a stainless BBQ.

Is there a non destructive test to do to check for good quality
stainless? I don't imagine that Home depot would be happy to see me going
at
the side of a new bbq with an angle grinder to look at the sparks. I
suppose
a magnet would be one way. Any other checks a person could make to
guarantee
quality stainless before buying?

Has anyone bought a stainless BBQ that has started to show signs of rust
that would care to comment??


Thanks...Jimi


Take a magnet with you. I'll leave it to you to decide how the test
works.

PS, steel (iron) rusts.

So do several SS alloys - especially after they've been heated.

Some of those react well to acidic SS cleaners - often sold for cookware -
that act as mild passivators.




My point is, the less a magnet sticks, the less likely it is to rust.
Less ferrite=less rust. The typical stainless that won't rust at all
will not attract a magnet at all.
