The
combination of a near flawless surface and proper passivation
results in the finest stainless steel fittings available.
Corrosion
attacks stainless steel and is always visible in the form of black
colored roughness. Although this is dangerous, it is rarely seen in
current use, except in cases where martensitic (HR) steel is in
total, prolonged immersion. This use is not recommended without
special precaution, periodic inspections, sacrificial anodes,
regular replacement of spare parts, and so forth.
What people erroneously call corrosion is really rust, or oxidation.
This is due to outside causes, such as pollution in the environment,
the presence of minute metal filings, contact with ferrous metal,
etc. This kind of contamination does not affect the structure of the
steel.

In the marine
environment, stainless steel is subject to considerable aggressive
forces. It is not stable. All stainless steels demands a minimum
upkeep, such as regular rinsing, the use of chrome-plated tools,
even re-passivation, which can be accomplished with our passivator
called Wichinox.
In the special
case of marine knives, the stainless steel selected ensures perfect
cutting, but it is more sensitive to corrosion and contamination.
Looking after marine stainless steel is just the same as cleaning
food-quality stainless steel, it requires regular care. Rinsing in
fresh water and greasing are recommended.
