ANSI B16.5/ASTM B381 Standard Gr7 titanium alloyFlange is a high-performance material, which is widely used in various industrial fields due to its excellent corrosion resistance, high specific strength and good processing performance. This article will introduce the chemical composition, mechanical properties, heat treatment, low-temperature impact test, main application scenarios and supply cases of Gr7 titanium alloy by TJC Group in detail.

 

1. Chemical composition

The chemical composition of Gr7 titanium alloy is as follows: titanium base alloy, containing 5% aluminum and 4% vanadium, with trace amounts of iron, oxygen, carbon, hydrogen and nitrogen. The mechanical properties and corrosion resistance of titanium alloys are closely related to their chemical composition and microstructure. In the production of Gr7 titanium alloy, strict control of the chemical composition and microstructure is necessary to ensure its excellent performance.

 

2. Mechanical properties

The mechanical properties of Gr7 titanium alloy are excellent, with high specific strength and good ductility. The Tendile and Yield Strengths of Gr7 titanium alloy are higher than those of ordinary titanium alloys, and its elongation is also very good. In addition, Gr7 titanium alloy has good fatigue resistance and creep resistance at high temperatures, which can meet the requirements of long-term use in harsh environments.

 

3. Heat treatment

The heat treatment of Gr7 titanium alloy is very important for its performance. Common heat treatment methods include annealing, quenching and tempering. Annealing treatment can refine the grain size and remove internal stress, while quenching and tempering can improve the strength and toughness of the material. The heat treatment process should be strictly controlled to ensure that the material has good performance and reliability.

 

4. Low-temperature impact test

The low-temperature impact test is an important index to evaluate the performance of titanium alloys at low temperatures. According to different test standards, Gr7 titanium alloy can withstand low-temperature impact loading without brittle fracture or obvious plastic deformation, which shows that it has good low-temperature performance and can be used in low-temperature environments.

 

5. Main application scenarios

Gr7 titanium alloy has been widely used in the petroleum and chemical industries, shipbuilding, aerospace and other fields due to its excellent performance. In the petroleum and chemical industries, Gr7 titanium alloy can be used in pipelines, valves and other components that require corrosion resistance and high pressure resistance. In shipbuilding, it can be used in hull structures, propellers and other parts that require good corrosion resistance and fatigue resistance. In aerospace, Gr7 titanium alloy can be used in airframe structures, landing gear and other parts that require high strength and lightweight.
