Titanium bolts are the same as ordinary stainless steel bolts and steel bolts, but the raw materials used are different.
Titanium bolts use titanium materials, and the general titanium materials are pure titanium Gr2 and titanium alloy Gr5. The raw materials of titanium bolts are relatively expensive, and the bolts made are also very beautiful, like handicrafts.
As the raw material for titanium bolts, titanium is a highly active metal.
Compared with traditional steel bolts, titanium bolts are stronger. The tensile strength of pure titanium can reach up to 180kg/mm², and titanium alloys are weaker than pure titanium bolts due to the addition of other metal elements, and some steels are stronger than titanium alloy, but in general, the specific strength (ratio of tensile strength and density) of titanium alloy exceeds that of high-quality steel.
Regarding the strength of titanium bolts and steel bolts, somebody did an experiment with a hydraulic press. Through this experiment, we can clearly see that the strength of titanium bolts is higher than that of steel bolts and stainless steel bolts.
Not only the strength, titanium bolts also have the following advantages:
1. The flexibility and oxidation resistance of titanium bolts are better, and they are more widely used in various industries.
2. In a high-pressure environment, titanium bolts have stronger compressive capacity than ordinary steel bolts, so titanium alloys are chosen for aerospace metals, and titanium bolts are used as connecting parts.
3. Titanium bolts are lighter in weight. Titanium is stronger and more resistant to deformation than steel, but the weight is only half of the steel. In modern industry, titanium has become a very important structural material.
4. Titanium bolts are more corrosion resistant than steel bolts.
5. Titanium bolts made of titanium alloy have good heat resistance strength, low temperature toughness and fracture toughness.
Based on the above advantages, steel has been replaced by titanium alloys in modern aircraft carriers, rockets, missiles, aircraft manufacturing, automobiles and other large and complex components.
