Titanium has good alkali titanium bar

Titanium has good alkali solution in the majority of the corrosion resistance, the corrosion rate of the solution with increasing concentration and temperature, aerobic, ammonia or an alkali solution in the presence of carbon dioxide, medical titanium bar will accelerate the corrosion of titanium, containing peroxide the alkaline solution of hydrogen, the titanium corrosion is poor. But in the sodium hydroxide solution also has strong corrosion resistance. Such as titanium at 130 ℃, 73% sodium hydroxide solution in the corrosion rate of only 0.18mm / a, titanium and other metals, the difference is that it does not cause stress corrosion cracking in sodium hydroxide solution, but long-term exposure may hydrogen embrittlement. Therefore, the use of titanium and other temperature caustic titanium bars for sale concentration of the alkali solution should be ≤93.33 ℃. Table 2-7 summarizes the corrosion resistance of titanium in a variety of environments.
Not difficult to see from the above, titanium is the most corrosion resistant chemical industry, the most promising corrosion resistant material, is particularly worth noting that it is dynamic and static seawater and marine atmosphere are completely corrosion resistant, medical grade titanium alloy even more than some of the resistance corrosion materials.
