Specific Applications

1. Exhaust system:Inconel 625 Tube is used to manufacture tail pipes and decoupling elements of automotive exhaust systems. These parts need to work for a long time in high temperature and corrosive environments, and the excellent corrosion resistance and high temperature stability of Inconel 625 make it an ideal choice. For example, Inconel 625 can resist the corrosion of rain and salt water, maintain the appearance and structural integrity of the tail pipe, and will not fail even at high temperatures.
2. Turbocharger:Inconel 625 Tube is used to manufacture turbocharger parts that need to work in high temperature and high pressure environments. The high strength and good toughness of Inconel 625 enable it to withstand high stress and thermal fatigue. For example, Inconel 625 is used to manufacture turbine blades and housings of turbochargers, ensuring stability and durability under high-speed rotation and extreme temperature conditions.
3. Sensors and electronic components:Inconel 625 Tube is used to manufacture sensors and electronic components in automobiles, such as oxygen sensors (Lambda sensors) and bursting discs of airbags. These parts need to maintain stable performance in high temperature and corrosive environments. For example, Inconel 625 is used to manufacture contact springs for oxygen sensors, ensuring that the sensors maintain high accuracy and reliability over long-term use.

Advantages and Characteristics

• Excellent high temperature resistance:Inconel 625 Tube has excellent stability in high temperature environments and can withstand working temperatures up to 980°C. A protective chromium oxide film formed on the surface of the alloy effectively prevents further oxidation.
• Excellent corrosion resistance:Inconel 625 Tube performs well in a variety of corrosive environments, especially in chloride media, with excellent resistance to pitting and crevice corrosion. Its high chromium and molybdenum content enables it to maintain good corrosion resistance in both oxidizing and non-oxidizing environments.
• Good mechanical properties:Inconel 625 Tube not only maintains high strength and hardness at high temperatures, but also has good plasticity and toughness. Its yield strength and tensile strength are relatively high, making it perform well when subjected to mechanical stress.
• Low thermal expansion coefficient:Inconel 625 Tube has a relatively low thermal expansion coefficient, which means that its size changes less when the temperature changes. This feature allows it to maintain a stable shape in high-temperature applications and reduce structural damage caused by thermal expansion.
