Gr12 Grade ASTM B381 Titanium Rings OD156.575*107.077.267.065 mm Ultrasonic Testing

The good mechanical properties of titanium ring as a structural material are achieved by strictly controlling the appropriate impurity content and adding alloying elements. Titanium ring is an ideal material for aircraft and engine because of its high specific strength, good mechanical properties and good corrosion resistance. With the development of machining technology, titanium alloy has been widely used in the manufacture of compressor section, engine hood, exhaust device and other structural frame parts of aircraft engine in recent years. Now titanium and titanium alloy are widely used in deep submersible, icebreaker, hydrofoil, hovercraft, minesweeper, propeller, whip antenna, seawater pipeline, condenser, heat exchanger, petroleum equipment, chemical equipment, sports equipment, automobile manufacturing, medical equipment, tools and so on. Mainly using its excellent corrosion resistance, and low density, memory, non-magnetic.

The properties of titanium are closely related to temperature, morphology and purity. Dense titanium is fairly stable in nature, but powder titanium can cause spontaneous combustion in air. The presence of impurities in titanium significantly affects the physical, chemical, mechanical properties and corrosion resistance of titanium. In particular, some interstitial impurities can distort the crystal lattice of titanium and affect various properties of titanium. At room temperature, the chemical activity of titanium is very small and can react with a few substances such as hydrofluoric acid, but when the temperature increases, the activity of titanium increases rapidly, especially at high temperature, titanium can react violently with many substances.At present, many countries have developed a variety of advanced titanium submersible, submarine, submarine laboratory equipment to carry out Marine research. In addition, titanium equipment and devices are widely used in coastal power stations, offshore oil production equipment, seawater desalination, Marine chemical production and mariculture. Titanium's lightweight, high-strength properties have long been on the radar of automakers.

Main advantages and applications:

1. Low density.

2. Higher than strength.

3. Small elastic modulus;

4. High fatigue strength, suitable for spring;

5. Low coefficient of thermal expansion.

6. Good corrosion resistance.

8. Good formability.
