Titanium hardware in seawater has very excellent corrosion resistance, especially in seawater, titanium corrosion resistance is 100 times that of stainless steel, titanium is all in natural water the most corrosion-resistant metal material. Titanium hardware in high temperature water and water vapor (such as >300 ° C) may be some discoloration or loss of light, and even a little weight gain, but will not cause corrosion. Titanium is very resistant to corrosion in seawater at temperatures up to 260 ° C. Titanium tube condensing devices have been used in polluted seawater for more than 20 years, and only slight discoloration has been found without signs of corrosion.


The resistance of industrial pure titanium hardware to crevice corrosion, point corrosion and impact corrosion in seawater is relatively good. The sensitivity of stress corrosion and corrosion fatigue is not serious. In high velocity flowing seawater (e.g. 36.6m/s), the erosion rate is somewhat increased. When the seawater contains frictional particles such as sand particles, it has some effect on the erosion resistance of titanium, but it is not as serious as copper alloys and aluminum alloys. In seawater, titanium hardware is also the most ideal material to resist cavitation corrosion. Titanium hardware is widely used in offshore oil and gas development, seawater desalination, ships, Marine fisheries and Marine heat energy conversion. At present, titanium for Marine engineering has become one of the main fields of civil application of titanium.
