Here’s a more detailed table to compare the material properties of Grade 1 and Grade 2 titanium alloys, which are commonly used in the manufacturing of Class 300 raised face weld neck flanges (WNRF).
| Property | Grade 1 Titanium | Grade 2 Titanium |
|---|---|---|
| Composition | 99.5% pure titanium | Titanium with small amounts of iron and oxygen |
| Tensile Strength (ksi) | 35-45 ksi | 50-60 ksi |
| Yield Strength (ksi) | 20-30 ksi | 40-50 ksi |
| Elongation | 24% | 20% |
| Hardness (Brinell) | 120 | 140 |
| Density (g/cm³) | 4.51 | 4.51 |
| Corrosion Resistance | Excellent, especially in fresh and marine waters | Excellent, superior in chloride environments |
| Applications | Less demanding, non-pressurized systems | Higher pressure systems, industrial water supply |
