Choose Titanium (Grade 5) When
- ✓ Weight is critical
- ✓ Oxidizing environments
- ✓ Cost-sensitive but need corrosion resistance
- ✓ Operating below 400°C
Choose Inconel 625 When
- ✓ High temperature > 400°C required
- ✓ Reducing acid environments
- ✓ Combined high temp + corrosion
- ✓ Nuclear or extreme chemical exposure
