What Are The Performance Criteria For Titanium Fittings?
Apr 09, 2024
What are the performance standards for titanium fittings? The standard for titanium fittings first appeared in the U.S. Aerospace Standard, the only internationally available standard for titanium fittings for the chemical industry is ASTM B363, which is also the document often followed in international trade of titanium fittings, ASTM B363 was established in 1961, the first modification was made in 1978, and has been modified several times since then (e.g., 83, 87), and the most recent version is 1995, which has made the standard more complete. The most recent edition was in 1995, making the standard more complete.
| Grade | Description |
|---|---|
| Ti Grade 1 (CP Ti) | Relatively low-strength and high-ductility pure titanium (Cp). |
| Ti Grade 2 (CP Ti) | Medium-strength pure titanium (Cp). |
| Ti Grade 3 (CP Ti) | High strength pure titanium (Cp). |
| Ti Grade 7 | Medium-strength Pd-alloyed titanium for enhanced corrosion properties. |
| Ti Grade 9 | High-strength titanium alloyed with 3% Al and 2.5% V. |
| Ti Grade 11 | Low-strength titanium plus 0.12-0.25% Pd for enhanced corrosion properties. |
| Ti Grade 12 | High-strength titanium alloy plus 0.3% Mo and 0.8% Ni for enhanced corrosion properties. |
| Ti Grade 16 | Medium-strength titanium plus 0.04-0.08% Pd for enhanced corrosion properties. |
| Ti Grade 17 | Low-strength titanium plus 0.04-0.08% Pd for enhanced corrosion properties. |
| Ti Grade 26 | Medium-strength titanium plus 0.08-0.14% Ru for enhanced corrosion properties. |
| Ti Grade 28 | High-strength titanium alloy plus 3% Al, 2.5% V and 0.08%-0.14% Ru for enhanced corrosion properties. |
