2. Titanium Grades: Material Properties of Grade 1 and Grade 2 Titanium

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
  • Grade 1 Titanium is more corrosion-resistant and less prone to fatigue but is less strong compared to Grade 2 Titanium. It is ideal for less critical applications.
  • Grade 2 Titanium is stronger, making it suitable for higher pressure and more aggressive environments, often chosen for industrial water supply and municipal systems.
3. Bolt Size and Torque Specifications for Class 300 Titanium Flanges

Proper bolt selection and torque application are essential to ensure a secure, leak-free connection between flanges. The table below provides the bolt size and the torque values for Class 300 Raised Face Weld Neck Flanges (WNRF) made from Grade 1 and Grade 2 titanium.

Nominal Pipe Size (NPS) Bolt Size (inches) Number of Bolts Torque (ft-lbs)
1/2" 5/8" 4 40-50
1" 3/4" 4 50-70
2" 7/8" 8 70-90
4" 1-1/8" 8 100-120
6" 1-1/4" 12 130-160
12" 1-1/2" 16 200-250
24" 1-3/4" 20 350-400
  • Note: Torque values should be adjusted depending on the gasket material used, as titanium has low friction, requiring specific torque values to ensure effective sealing.
