Widely used in industries of petrol, chemistry, carbamide,etc Hastelloy B Having strong resistance to hydrochloric acid of any consistance which is below boiling point. Resistable against vitriol, phosphate, hydrofluoricacid, organic acid etc which are oxidable acid, alkali and non-oxidable salt. Hastelloy C 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 reduces corrosion. Tantalum Having strong resistance to corrosive mediums that is similar with glass. Applicable to most chemical mediums. Except for hydrofluoric acid, oleum and alkali. Platinum-iridium Applicable to most chemical mediums except for ammonium salt.
