Titanium is a metallic chemical element, chemical symbol Ti, atomic number 22, in the periodic table of chemical elements in the fourth period, IVB group. It is a silver-white transition metal characterized by light weight, high strength, metallic luster and resistance to wet chlorine corrosion. But titanium can not be applied to dry chlorine gas, even if the temperature of dry chlorine gas below 0℃, there will be a violent chemical reaction to generate titanium tetrachloride, and then decomposition to generate titanium dichloride, or even combustion. Titanium remains reliable in chlorine only when the water content is above 0.5%

Compression spring is to bear the pressure of the spiral spring, it is used for the material cross-section is round, but also useful rectangular and multi-strand steel entangle coil, spring is generally equal pitch, compression spring shape: Cylindrical, conical, convex and concave and a small amount of non-circular, compression spring ring and ring between a certain gap, when subjected to external load when the spring contraction deformation, deformation energy storage. Compression Springs provide resistance to external load. Compression springs are generally coils of wire equal pitch and have a fixed wire diameter. Compression springs use multiple open coils to provide resistance to external pressure (such as gravity pushing down a wheel or the body pressing down on a mattress). That is, they push back against external pressure. Compression springs are generally coils of wire equal pitch and have a fixed wire diameter. In addition, there are conical compression springs, or a combination of conical and linear springs. Depending on the application, compression springs can be used to resist pressure and/or store energy. Round wires are the most commonly used compression springs, but there are also square, rectangular, and special-shaped wires made of compression springs.
