Incoloy 825 capillary tubing is a specialized form of tubing made from Incoloy 825, a nickel-iron-chromium alloy known for its exceptional corrosion resistance and versatility. This tubing is designed for applications requiring precise control and resistance to corrosive environments. In this article, we will explore the uses, properties, and applications of Incoloy 825 capillary tubing.
Incoloy 825 is a nickel-based alloy that includes significant amounts of iron, chromium, molybdenum, copper, and titanium. This composition provides excellent resistance to both oxidizing and reducing acids, making it ideal for environments where corrosion is a significant concern. The alloy's ability to withstand chloride stress corrosion cracking is particularly valuable in marine and chemical processing applications.
Incoloy 825 capillary tubing is manufactured to have a smaller diameter and precise thickness, which makes it suitable for applications requiring high precision and control. The tubing can be produced in both seamless and welded forms, with various surface finishes available to meet specific requirements.
The chemical composition of Incoloy 825 includes:
- Nickel (Ni): 38-46%
- Iron (Fe): 22%
- Chromium (Cr): 19.5-23.5%
- Molybdenum (Mo): 2.50-3.50%
- Copper (Cu): 1.50-3.0%
- Manganese (Mn): 1%
- Titanium (Ti): 0.60-1.20%
- Silicon (Si): 0.50%
- Aluminum (Al): 0.20%
- Carbon (C): 0.050%
- Sulfur (S): 0.030%
Incoloy 825 has a density of approximately 8.14 g/cm³ and a melting range of 1370-1400°C. Its mechanical properties include a tensile strength of at least 586 MPa and a yield strength of at least 241 MPa.
