Typical Applications
|
For
corrosion resistance in the chemical, petrochemical and marine
industries, especially in oxidizing environments.
|
For
corrosion resistance where media are strongly reducing to medium
oxidizing.
|
Best
corrosion resistance of all typically used metals;Good for strong
oxidizing to strong reducing environment.
|
Very
good corrosion resistance, especially in strong nitric acid service.
