.
Resistant to :
Atmospheric corrosion: formation of the a greenish protective
patina due to the formation of copper basic salts (such
sulphates, chlorides in marine environment, nitrates and
carbonates). Cu-DHP has a good resistance in in natural and
industrial atmosphere (maritime air too). Water (industrial and
drinking): up to flow rate of 1,5 .. 2 m/s for cold water, above
60ï¿½C velocity should be limited to 0.6 .. 0.9 m/s. Aqueous and
alkaline solutions (not oxidizing), pure water vapour (steam),
non oxidizing acids (without oxygen in solution), neutral saline
solutions. Material can be heat-treated in reducing atmosphere.
Practically resistant against stress corrosion cracking .
Not resistant to: :
Rapid attack in oxidising acids, oxidising heavy-metal salts and
sulphur. As well in gases or liquids containing ammonia,
cyanide or halogens. hydrous ammonia and halogenated gases,
seawater especially at high flow rates. .
