Note: 1. Corrosion resistance grade is divided into three levels: Excellent - corrosion resistance, corrosion rate is below 0.127mm / a. Good - moderate corrosion resistance, corrosion rate between 0.127-1.27mm / a. Poor - not resistant to corrosion, corrosion rate is above 1.27mm / a.
2. Pure titanium in most media, especially those with high corrosion resistance in a neutral, oxidizing medium and sea water. Titanium in seawater corrosion resistance than aluminum alloy, stainless steel and nickel alloys is higher in the air industry, agriculture and marine environment, although a few years, is not discolored surface. Hydrofluoric acid, sulfuric acid, hydrochloric acid, orthophosphoric acid and some hot concentrated organic acids have a greater corrosion to titanium (see table above), and hydrofluoric acid has a high corrosive effect on titanium regardless of concentration and temperature. Titanium has high stability to various concentrations of nitric acid and chromic acid, and has high corrosion resistance in alkali solutions and most organic acid and inorganic salt solutions.
3. Titanium does not undergo local corrosion and intergranular corrosion, and corrosion is performed uniformly.
4. The corrosion resistance of titanium alloys is similar to that of industrial pure titanium, which is why titanium alloys are widely used in the chemical and shipbuilding industries.
The design of middle through hole is easy to install, Barrel Damper is usually used in small spaces. ABD barrel dampers are the perfect solution for a wide range of applications. Barrel dampers are widely used in automobile interior decoration, household electric appliances, furniture, hidden socket, etc. Our dampers can make the movement of structures soft, quiet and safe to mitigate the impact, avoid the damage, increase the mechanical life, reduce noise, and improve product quality.
