Metals are rarely present in the native state (i.e. not combined with another element) in nature. However the case of copper or gold can be mentioned.

But it is not the case of iron which has a high affinity with oxygen and finds a balance by combining with it to form oxides. Iron, pure or allied, tends to oxidize or more generally to corrode to achieve a state of balance, in most of the planet's weather conditions. Very early on in history, man discovered and started treating the phenomenon of corrosion.

The different types of corrosion suffered by the steels used by ADIAMAS™ mainly belong to the category of water corrosion.These environments are not very harsh (weak acidity or base). According to their temper and type, stainless steels have different sensitivity to corrosion, which comes in various forms of which the main ones are cavernous corrosion and pitting corrosion.
