Main performances of the electrode materials 

Stainless steel SUS316: 

Applicable in water, sewage and corrosive mediums. Widely used in industries of petrol, chemistry, carbamide, etc

Stainless steel: 

Covered with tungsten carbide Applicable in mediums of no corrosive and low abrasion. 

Hastelloy B(HB): 

Having strong resistance to hydrochloric acid of any consistance which is below bioling piont. Also resistable against vitriol, phosphate, hydrofluoricacid, organic acid etc which are oxidable acid, alkali and non-oxidable salt. 

Hastelloy C(HC): 

Be resistant to oxidable acid such as nitric acid, mixed acid as well as oxidable salt such as Fe+++, Cu++and sea water

Titanium: 

Applicable in seawater, and kinds of chloride, hypochlorite salt, oxidable acid(including fuming nitric acid), organic acid, alkali etc. Not resistant to a pure reducing acid(such as sulphuric acid, hydrochloric acid)corrosion. But if acid contains antioxidant(such as Fe+++, Cu++)is greatly reduce corrosion. 

Tantalum: 

Having strong resistance to corrosive mediums that is similar with glass. Almost applicable in all chemical mediums. Except for hydrofluoric acid, oleum and alkali. 

Platinum-iridium: 

Almost be applicable in all chemical mediums except for aqua fortis, ammonium salt.
