Shower caddy follow up

Umm.. claimed to be brushed stainless steel. Looks more like good quality chrome to me.

Non magnetic so not mild steel. I'll report back in a few years:-)

I'd say non magnetic means not chrome, rather borderline stainless. It's not going to be a chrome plated cuprous alloy.

[Andy Burns]

Actually, some of the Victorian Plumbing ones do claim to be chrome plated brass.

Some Kind of alloy maybe? Brian

Having acquired a Chinese stainless steel gate fitting, I learnt from this very group that some stainless steel is prone to surface rust when damp, despite its name.

[newshound]

Yes, standard in the old days. This chinese cheapie won't be, though.

[newshound]

Cheap cutlery is often marginal in chrome content, you can get rust spots that can just about be cleaned off with scotchbrite or similar.

[Chris J Dixon]

I think the usual response is that it doesn't claim to be stain-free. ;-)

Don't leave a Brillo pad on a damp SS sink.

Cutlery tends to be 18% chromium and is magnetic (para- only?); 18 10 isn't magnetic and shouldn't rust. I don't know what A2 st. st. is, but it withstands 10 years+ of salt.

Rolls Royce wheel trim was 22% chromium and hard chrome plated and polished

- that didn't rust in 72 hr. salt spray but the 18% did.

[Tim Lamb]

Yes. We have some Japanese stainless steel cutlery which can pick up spots of rust in the dishwasher. Interestingly, while I was testing the caddy, I discovered that the knife blades are magnetic but nothing else.

A bit of a simplification. 18Cr 8Ni is austenitic, and non magnetic. Ferritic stainless steels are 13 to 18% Cr and are magnetic.

I'd bet that the (non-magnetic) caddy is austenitic stainless. It might suffer rust spotting or staining in some circumstances (like the steel wool case mentioned elsewhere)

; 18 10 isn't

ICBA to look it up properly. "A2" tends to be the base designation for stainless steel screws and fasteners, I think it is normally austenitic.

"A4" is sometimes called marine grade stainless, that will definitely withstand salt, it has a higher content of alloying elements and will definitely be austenitic.

That's what I would call a Rolls Royce solution.

[Tim Lamb]

Oh well! If we are all still here in 3 or so years I'll report back:-)
