Technical data  :      

Technical Performance Parameters


Main performances of the electrode materials

Electrode material


sainless 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++aStnd sea water


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 is greatly reduce corrosion.


Having strong resistance to corrosive mediums that is similar with glass

Almost is applicable to all chemical mediums.

Except for hydrofluoric acid,oleum and alkali.


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