The addition of other metals makes steel stainless.
Because it stains less easier than regular steel. It's not 'stain proof', it's just more resistant to staining and rusting. Think of it as stain less.
Stainless steel is a steal alloy with a minimum of 10% chromium.

its stainless It does not rust, hence the name stain less
It is far less likely to stain than normal steel, but it can in certain conditions.
Steel is simply iron with a small percentage of carbon. It oxidizes (rusts) easily. Stainless steel has added chromium, but also may contain any of the following: nickel, niobium, molybdenum, or titanium. Stainlees steels form a very thin layer of chromium oxide on the surface which protects it from further oxidation. While stainless is not stain-proof, it does stain less than carbon steel. Most stainless steels are non-magnetic, or very weakly magnetic.
Stainless steel in metallurgical definition is a steel that contains ~14% or more Chromium. Other alloying elements such as Nickel can also improve steel's stain resistance properties. The amount of free Chromium, i.e. not tied up in carbides determines steel's stain resistance ability. Higher carbon content leaves less free Chromium in the alloy, which explains why some of the high end stainless steels with more % of Chromium are less stain resistant than lower grade stainless steels with less Chromium and Carbon. However, given time and conditions all steels will rust. For more information on alloying elements effects on the steel see the related links.
Yes you can, just clean the old stain with steel wool or fine sandpaper before you do.
Stainless Steel contains between 10 1/2 and 11% Chromium. The layer of Chromium Oxide keeps the steel from rusting. It's interesting to note that Stainless Steel is called that because it "Stains Less". That does not mean that is is stain PROOF.
why yes, yes you can it wont stain hence the name stainless steel.
By thick control.
To effectively remove a tea stain from stainless steel, mix baking soda with water to form a paste. Apply the paste to the stain and let it sit for a few minutes. Then, scrub the stain with a soft cloth or sponge. Rinse the area with water and dry it thoroughly.
