Raskt svar
Titanium: lighter weight, superior corrosion resistance, higher strength-to-weight ratio, more expensive. Stainless steel (316L): cost-effective, good corrosion resistance, heavier. Choose titanium for deep sea, weight-critical, or highly corrosive environments.

When to Choose Titanium
- Deep sea applications: >3000m depth
- Weight critical: AUVs, portable equipment
- Highly corrosive: Hot vents, chemical exposure
- Long-term deployment: Years underwater
- High pressure: Hadal zone applications
When to Choose Stainless Steel
- Shallow water: <1000m depth
- Cost sensitive: Budsjettbevisste prosjekter
- Short-term use: Temporary deployments
- Standard applications: ROV, sensors, general use
- Freshwater: Lakes, rivers (less corrosive)
Weight Savings Example
For a typical connector housing:
- Stainless steel: 500g
- Titan: 275g (45% weight reduction)
