Titanium screws have strong corrosion resistance, but it will be also corroded quickly under certain special conditions.

How can we avoid the disadvantages caused by corrosion of titanium screws? The first thing to understand is how the titanium screws are corroded.

The concept of the corrosion rate of titanium screws is basically only applicable to general corrosion or general corrosion. How do you distinguish between the two cases?

Special corrosion form of titanium screws

For pure titanium(Titanium Grade2), corrosion damage, especially equipment damage, cannot usually be characterized and judged by the corrosion rate, and the corrosion loss per unit area or the corrosion depth per unit area. Because the corrosion of titanium is basically in the form of local corrosion damage, although it is not unique to titanium.At least titanium can be made particularly prominent.

The most popular titanium fasteners are DIN933 Hexagon bolt and DIN934 Hexagon nut.

Therefore, on the basis of understanding the overall corrosion of titanium screws, the local part of titanium is discussed. Corrosion is an indispensable and inseparable component. It may be said that it is of particular importance for the selection of titanium screws.

The local corrosion forms of titanium screws are particularly prominent in combustion and ignition, hydrogen absorption and hydrogen embrittlement, pitting corrosion, crevice corrosion and weld corrosion. Among them, combustion, ignition, hydrogen absorption and hydrogen embrittlement are particularly serious forms of corrosion damage.

If you encounter these problems during the use of titanium screws, be sure to check the corrosion of the titanium screws in time to ensure better operation.
