1. Overview of BEM Exchanger, ASME SB338 GR.2
ASTM SB338 Grade 2 Titanium is a commercially pure titanium alloy widely used in heat exchanger applications. It is known for its excellent corrosion resistance, low density, and high strength-to-weight ratio. These properties make it an excellent choice for high-performance heat exchangers, particularly in environments where chemical resistance and thermal efficiency are critical.
Chemical Composition of BEM Exchanger, ASME SB338 GR.2
| Element | Composition (%) |
| Titanium (Ti) | Balance |
| Iron (Fe) | ≤ 0.30 |
| Carbon (C) | ≤ 0.08 |
| Nitrogen (N) | ≤ 0.03 |
| Hydrogen (H) | ≤ 0.015 |
| Oxygen (O) | ≤ 0.25 |
The low impurity levels in Grade 2 titanium contribute to its excellent corrosion resistance and mechanical properties, making it suitable for harsh and aggressive environments.
Mechanical Properties of BEM Exchanger, ASME SB338 GR.2
| Property | Value |
| Tensile Strength | ≥ 345 MPa (50,000 psi) |
| Yield Strength | ≥ 275 MPa (40,000 psi) |
| Elongation | ≥ 20% |
| Density | 4.51 g/cm³ |
These properties ensure the tubes can withstand high pressures and temperatures, making them ideal for use in heat exchangers where reliability and durability are critical.
