Electrode material

316L
|
K1
|
Nitric acid, sulfuric acid<5% at room temperature, oxalic acid, formic acid, alkaline solution, sulfite seawater under certain pressure, acetic acid and other media have strong corrosion resistance and are used in industrial applications such as petrochemicals, urea, and Vincennes
|
|
|
Hastelloy HB
|
K2
|
Has good corrosiveness to all acids below the sensitive point, and is also resistant to corrosion from non oxidizing acid, alkali, and non oxidizing salt solutions such as sulfuric acid, phosphoric acid, hydrofluoric acid, and organic acids
|
||
|
Hastelloy HC
|
K3
|
Capable of withstanding corrosion from nitric acid, mixed acid, or mixed media of chromic acid and sulfuric acid, as well as oxidation salts, or corrosion from hypochlorous acid solutions above room temperature in seawater
|
||
|
titanium
|
|
Capable of withstanding corrosion from seawater, various chlorides and hypochlorites, oxidizing acids (including fuming nitric acid), organic acids, alkalis, etc., but not resistant to corrosion from relatively pure reducing acids (such as sulfuric acid, hydrochloric acid). When the acid contains oxidants (such as nitric acid and media containing Fe, CU ions), corrosion is greatly reduced
|
||
|
tantalum
|
|
Has excellent corrosion resistance similar to glass, except for hydrofluoric acid and concentrated sulfuric acid, it can withstand almost all chemical media (including hydrochloric acid, nitric acid, and sulfuric acid below 175 ℃), and does not corrode in alkali
