What is INOX or stainless steel?

In 1913, English metalworker Harry Brearly, working on a project to improve the performance of the rifle pipe, accidentally discovered that adding chromium to a low-carbon steel yields resistance to damage or corrosion.

With the addition of steel, carbon and chrome, modern stainless steel can also contain nickel, molybdenum and titanium.

Nickel, molybdenum and chrome increase the corrosion resistance of stainless steel. It is understood that adding a minimum of 12% of chromium steel allows it to be resistant to corrosion. Chromium combines with oxygen from the atmosphere in a steel and a thin, invisible layer called a "passive film" is formed.

The magnitude of the chromium and oxygen atom are similar in that they coincide adherently to each other on the surface of the metal, forming a stable layer of thickness of only a few atoms.

If the metal surface is scratched or otherwise damaged by the protective layer, more oxygen will quickly accumulate in the place and form and recover the exposed surface, thus protecting it from further corrosion.

Care should be taken that stainless steel has poor corrosion resistance in environments with little or no oxygen circulation.
