13.1 INFORMATION ABOUT STAINLESS STEELS

Stainless steel is a steel grade designed that a thin protective sheet is formed on the metallic surface, which protects it against corrosion
(Oxide film resulting from the chemical reaction of oxygen on the metallic surface).
Anything hindering the formation of this sheet, or facilitating its partial destruction (Food residues, overflow of liquids, stagnant liquids...)
reduces the resistance of stainless steel to corrosion.
Whilst the composition of stainless steel enables it to withstand some chemical aggression better than classical steels, you must not think
that stainless steel is indestructible.
3 main factors contributing to corrosion should be watched for:
- The chemical environment in general:
- The temperature:
- The duration:

13. MAINTENANCE

* Different brines (Salt concentration, Sauerkraut...)
* Chlorides contained in particular in:
Any chemical environment is made considerably more aggressive to stainless
steel as the temperature rises.
The longer the contact time between stainless steel and the chemicals, the more
noticeable the consequences of corrosion will be.
