Applications
|
|
Stainless Steel 316L
|
Applicable in water,sewage and corrosive mediums.Widely used in industries of petrol,chemistry,carbamide,etc
|
|
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
|
|
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 is greatly reduce corrosion.
|
|
Tantalum
|
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.
|
|
Platinum-iridium
|
Almost be applicable in all chemical mediums except for ammonium salt.
|
|
Stainless Steel Covered
Tungsten Carbide
|
Applicable in mediums of no corrosive and low abrasion.
