Life seems to throw up new problems all the time..
Ive noticed quite a few st steel items Ive bought recently have started to go rusty and corode, even the ones indoors, like our 2 year old Russell Hobbs kettle, round the edge of the lid there is rust.
Also the st steel BBQ I bought about 3 years ago has corrosion all over it.
There seems to be a lot of st steel products made in China and this so called st steel has a large amount of iron in it.....I mean can it even be called st steel, isn't the idea of st steel that it doesn't corode ?
One way to detect wether an item you are looking at contains a lot of iron is to take a magnet with you and see if its magnetic, good quality st steel isn't as it has more chrome present.
info from wiki
Stainless steel differs from carbon steel by the amount of chromium present. Unprotected carbon steel rusts readily when exposed to air and moisture. This iron oxide film (the rust) is active and accelerates corrosion by forming more iron oxide, and due to the greater volume of the iron oxide this tends to flake and fall away. Stainless steels contain sufficient chromium to form a passive film of chromium oxide, which prevents further surface corrosion by blocking oxygen diffusion to the steel surface and blocks corrosion from spreading into the metal's internal structure, and due to the similar size of the steel and oxide ions they bond very strongly and remain attached to the surface
