- Titanium is used as a sheath material for mineral insulated (MI) cables and thermocouples due to its excellent corrosion resistance.
- Titanium sheaths are resistant to seawater, chlorides, and oxidizing acids, making them suitable for harsh chemical environments.
- Titanium alloys such as AISI 316Ti and AISI 321 improve high-temperature strength and resistance to intergranular corrosion.
- Titanium sheathed MI cables are widely used in aerospace, chemical processing, and high-temperature welded equipment applications.
Titanium (Ti) can be used as a specialized sheath material for MI cable and high temperature thermocouples. In this case it offers good resistance to corrosion in a wide range of substances.
Titanium can also be included in stainless steel alloys: AISI 316Ti and AISI 321. The addition of titanium helps prevent carbide precipitation and thus avoids intergranular corrosion and improves mechanical strength. .
Titanium’s physical properties
- Melting point: 1725°C
- Excellent mechanical strength between 150°C and 470°C
- Resistant to
- Oxidizing acids
- Inorganic chloride solutions, moist chloride gas and chlorinated organic compounds
- Salt water and sea water
These properties apply to the stainless steel titanium alloys, only the temperatures vary as follows:
| Maximum working temperature | Melting point | |
|---|---|---|
| AISI 316Ti | 900°C | 1370°C |
| AISI 321 | 1090°C | 1350°C |
Industrial applications of titanium
Used as a sheath material for MI cable that is exposed to highly corrosive substances and high temperatures.When added to stainless steel it creates an alloy that is especially chosen for welded components and high temperatures, corrosive environments. Such industries would include:
- Aircraft exhausts & manifolds
- Jet engine parts
- Stack liners
- Welded equipment
- Chemical processing equipment
