Stainless steel kitchen sinks. Scratch removal kit
As is the case with just about anything you purchase, you get what you pay for and that certainly applies to stainless steel sinks. Did you know that stainless steel does not necessarily means that your sink will not stain? It all depends on the steel's composition.
There are basically two things that determine the price tag for a stainless steel sink; gauge (thickness) and chromium/nickel content. So let's have a quick look at what what you should know about stainless steel kitchen sinks.

Unfortunately "Stainless Steel" doesn't always means that the sink will not stain. Stainless steel comes in different grades of metal composition. Chromium provides strength to the steel while nickel makes it more durable. So, let us have a closer look at the numbers that are used in advertising or on store labeling.
To make steel into stainless steel a minimum of 12% chromium has to be added to the steel. The chromium in the steel combines with oxygen in the atmosphere to form a thin, invisible layer of chrome-containing oxide. The chromium will resist rust, or stain 'less' than other types of steel. If you want a stainless steel kitchen sink that not only looks good but also will last you should be looking for a sink with a high nickel content.
An 18/10 stainless steel sink would be a good choice (18% chromium for lustre and rust protection and 10% nickel for hardness and strength).
Sometimes the grade and quality of a stainless steel kitchen sink is indicated by a number. The most common grades are 201, 301, 302, 304 and 420.
A grade 201 sink is most often seen in the large home improvement stores on the lowest end of the price scale. As you progress into the higher grades, the steel becomes more corrosion, oxidation, and rust resistant. Choosing a kitchen sink made of 302 or 304 stainless steel would be a good choice.
