The corrosion resistance of grade 2 titanium

The corrosion resistance of grade 2 titanium is based on the presence of a stable, continuous, tightly adherent oxide layer. This layer forms spontaneously and immediately upon exposure to oxygen. If damaged, it re-forms readily as long as there is some source of oxygen (air or moisture) in the environment. In general, the higher the purity of Ti, the greater the corrosion resistance. grade 2 titanium sheet with its relatively low impurity levels, has been widely used because it is capable of performing well in many corrosion-critical applications such as marine environments and chemical processing. In seawater, it is fully resistant to corrosion at temperatures up to 315ºC (600ºF). The possibility of crevice corrosion must be considered, however, and components appropriately designed to avoid tight crevices.
