Stainless steel AISI 316L
Inox (or stainless) steel is an alloy made of iron which, together with the typical mechanical properties of steel, presents also peculiar characteristics of corrosion resistance.
This kind of steel contains high quantities of nickel and chrome which guarantee its optimal performance.
The basic properties of stainless steel AISI 316L are as follows:
- optimal corrosion resistance into fresh, industrial water and seawater;
- cleaning convenience.
These features make it an ideal “building material” to be installed in environments characterized by strongly aggressive agents, such as salty sea air in seaside localities or acid rains caused by environmental pollution.
ELECTROPOLISHING
Electropolishing is a superficial finishing process improving shape and functional characteristics of steel.
It is a galvanic process which selectively removes material from the superficial layer, by consequently improving the finish, which becomes shiny, smooth and clean, due to the progressive reduction of the protruding profile.
Electropolishing is followed by passivation, a chemical process aimed at enhancing the spontaneous formation of a protective oxide layer isolating the metal and preventing the oxidation reaction.
Therefore, the electropolished inox steel AISI 316L has a considerable resistance to the corrosion due to polluting environmental agents or to salty sea air.
