I think many of you are missing the point.
The arguments about the merits and properties ae largely superfluous
I actually have a degree in metallurgy and spent around 30 years heat
treating steels, some of them stainless steels
The watering can was sold to me as stainless steel I would not expect
it to start to rust after less than a year. It is not fit for purpose.
It is rather unlikely that I would use it to apply anaerobic seawater
to my plants!!!!!!!

Stainless steel is a name of a particular type of metal alloy, not a
description.

It was intended as being descriptive of the properties of cutlery made from
it, when first used. I think an earlier name, weather resistant iron, was
less misleading.

My neighbours in Frinton will be in revolt over that remark, but then
they are a pretty revolting lot.

I cannot understand all these anti-Tesco remarks. It is a supermarket
like any other - in fact more successful than the others, so plenty of
people must like what they do. If you don't, then shop somewhere else.
I find them convenient and cheap - but I do not buy their own brand
goods just as I don't buy any other supermarkets own brand goods
either.

That depends entirely whether the rust is impairing the can
cosmetically or structurally. I have had quite a lot of stainless
steel gods that have suffered cosmetic rust and, in things like
gardening equipment, there is no way that makes them unfit for
purpose.

Are you sure that they are "stainless steel" and not galvanised
because as far as i was aware s/s does not rust

Stainless Steel can rust, it depends on the grade and make up of
the Steel

Actually Mike is correct, it can rust, it just does so much less and
more slowly and a lot depends on which grade of steel is used.
Dead right. Having sailed yachts for 20+ years, S/S fittings and rails do
rust in time.

Can you get a sacrificial anode for a watering can? ;-)

There are even different grades of "marine grade" stainless. When I
built my yacht I did a bit of research. I used 316 stainless, which
is OK for salt water exposure but not the best. It was however more
easily available, being used in the food industry. I think 328 was a
lot better, but I may be misremembering. I only needed it for the
stanchions, nothing structural. It yellowed very slightly over the 5
years at sea, but still looked bright and uncorroded.

The other thing that can occur is electrolytic corrosion when the
stainless is in contact with a different metal. Don't bolt stainless
fittings to an aluminium mast!

Did it rust around the welds? I have seen inappropriate welding rods
being used on stainless.

If the whole can is made of the same metal and you are not going to immerse
it in salt water, sacrificial anodes will not be required as Electrolytic
action will not take place.

328 does not mean anything to me, but 316L, which is a low carbon version of
316, has better corrosion resistance. There is also implant quality 316,
which has been twice refined under vacuum, which is even better.

Before cadmium became a devil metal, cadmium plated steel screws were the
thing to use in aluminium.

Sorry, Mark, that one is now so old that we charge a fine for anybody
