The chemical compatibility and resistance of stainless steel depends on the specific type, grade of steel and the environment with which it comes into contact. There are many different types of stainless steel, each with its own chemical composition and properties. The most common grades include AISI 304 and AISI 316.
It is very important to select a type of stainless steel that is chemically compatible with the environment it will be in contact with. If you are unsure which type of stainless steel is suitable for your application, it is recommended to consult a specialist.
In addition to the chemical composition, the stability of stainless steel is also influenced by factors such as:
- Temperature: stainless steel becomes less resistant to corrosion as temperature increases.
- Concentration: more concentrated chemicals are more likely to corrode stainless steel than diluted ones.
- Flow rate: fast flowing chemicals can corrode stainless steel faster than slow flowing chemicals.
- Tension: stainless steel under tensioned is more susceptible to corrosion than non-tensioned steel.
It is important to consider all of these factors when selecting and using stainless steel.
- A - excellent;
- B - good;
- C - average or poor;
- D - not recommended.
