Main performances of the electrode materials
Electrode material	Applications
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.
