It has a quantity of Chromium (usually around 10%) added during the smelting process. The Chromium forms a 'film' on the surface - preventing rusting.
Stainless steel is a material that is the result of an alloy of chromium, iron, and carbon. The ability for stainless steel materials to resist rust is a chemical property.
Stainless reply: want to know steel grades other than stainless against corrosion
It depends on the applications. Stainless Steel is more corrosion resistant and more expensive. Carbon Steel is cheaper and less corrosion resistant.
In making a chemical reactor out of stainless steel, you'd get good resistance to corrosion. You'd also get the durability and toughness that something like, say, glass, could not provide. As regards a nuclear ractor, there is a lot of stainless steel used in nuclear reactor plumbing to resist corrosion. And it is cheaper than, say, the zircaloy that is used in the core itself.
Corrosion is a gradual destruction of metal by chemical reactions mixed with the environment. How long stainless steel can withstand corrosion depends on the thickness of the metal.
by covering with stainless steel
Stainless Steel is used because it has an higher corrosion resistance over normal steel.
No. Stainless Steel will resist contamination from the aluminum when they are used together.

Compared to 304 grade stainless steel, the 316 has higher strength, can withstand higher temperatures, and yes it can resist corrosion better. One factor is the molybdenum content in the 316 grade which gives it the overall corrosion resistant properties. The downside, 316 stainless steel grade is way more expensive than 304.
stainless steel has chromium added to the steel, which forms a protective oxide layer at the surface, preventing corrosion (rust).
Many stainless steels are stronger than mild steel. Stainless steel is also corrosion resistant to many different environments where mild steel is not.
