Stainless steel is what it says.
Its Steel, to which chromium and molebdnium have been added in small quantities. It makes, rust and corrosion prone steel, inert in most situations. No rust.
If you were to throw a clean non painted steel bearing, or lump of steel sheet, or steel bolt or screw into the garden, it would be rusty in a week, solid rust, red and destroyed 1 year later.
If you throw a bit of quality stainless steel, or stainless steel sheet, or stainless steel bolt, into your garden, then 5 years later, after you cleaned off dirt and bugs, the stainless steel would be exactly as good as new. And still shiny.
