Titanium fan

Pure titanium (TA2) plate fan, in the chlor alkali chemical industry is generally used in the low concentration of sulfuric acid, hydrochloric acid gas environment. Titanium is generally suitable for room temperature, 3% and 100 C, hydrochloric acid solution of 0.5%. Titanium is only suitable for low temperature sulfuric acid environment with low concentration, and sulfuric acid of 40% concentration will react with titanium. 1% hydrofluoric acid can react violently with titanium. Titanium is also widely used. Compared with the aluminum fan in the high temperature environment, acid corrosion resistant material, aluminum is much better than titanium. But the aluminum alkali resistance.
Hastelloy B-2 alloy has excellent corrosion resistance in various reducing media, can withstand any temperature under atmospheric pressure, any concentration of hydrochloric acid corrosion. In the inflated moderate concentrations of non oxidizing acid, phosphoric acid, acetic acid, high temperature and various concentrations of formic acid and other organic acids, bromate and hydrogen chloride gas has excellent corrosion resistance, corrosion resistance and at the same time, it is also a halogen catalyst.
Monel alloy in fluorine gas, hydrochloric acid, sulfuric acid, hydrofluoric acid and their derivatives have very excellent corrosion resistance. Acid medium: M400 in the concentration of sulfuric acid is less than 85% of the corrosion resistance. M400 is resistant to hydrofluoric acid is one of the most important material is very few. Water corrosion: M400 alloy in most water corrosion circumstances, not only excellent corrosion resistance, and pitting corrosion, stress corrosion is rarely found, corrosion rate is less than the highest temperature: high temperature corrosion of 0.025mm/a M400 continuous work in the air at 600 degrees C, in high temperature steam, the corrosion rate is less than 0.026mm/a. Ammonia: as Monel 400 alloy of nickel content is high, so it can withstand 585 DEG C and ammoniated under anhydrous ammonia corrosion.
The Cornell alloy, easy processing, high tensile strength, fatigue strength, creep strength and high fracture strength at 700 C, has high oxidation resistance at 1000 DEG C, has stable chemical properties at low temperature, good welding performance l metallographic structure
