Choose Titanium (Grade 5) When
- ✓ Weight savings critical (aerospace, racing)
- ✓ Seawater / chloride exposure
- ✓ Medical implant applications
- ✓ Long-term corrosion resistance needed
Choose Stainless Steel (316L) When
- ✓ Budget is primary concern
- ✓ General-purpose corrosion resistance sufficient
- ✓ Easy machinability required
- ✓ Standard shapes readily available
