Titanium Propeller Hub Cap is a marine-grade quietrunning submarine propeller component designed for Quiet-running submarine propeller hub cap. Fabricated from Grade 5 Ti-6Al-4V, it provides immunity to seawater corrosion, chloride stress corrosion cracking, and biofouling — eliminating the need for cathodic protection in submerged service.

Q: Is Titanium Propeller Hub Cap compatible with subsea cathodic protection systems? ▼
Grade 5 Ti-6Al-4V does not require cathodic protection (CP) in seawater. If CP is present from adjacent steel structures Titanium Propeller Hub Cap will not suffer hydrogen embrittlement at potentials more negative than -1050 mV (Ag/AgCl). However, direct electrical connection to aluminum anodes should be avoided for quietrunning submarine propeller as overprotection (>-1100 mV) can cause hydride formation.
Q: What is the typical lead time for Titanium Propeller Hub Cap orders? ▼
Standard lead time for Titanium Propeller Hub Cap is 15-25 business days depending on quantity and complexity. Rush orders (3-5 working days) are available for prototype evaluation. Sample evaluation (1-5 units) can be expedited to 5-7 business days. Volume pricing is available for production quantities above 100 units.
Q: What material certifications are provided with Titanium Propeller Hub Cap? ▼
Each Titanium Propeller Hub Cap shipment includes EN 10204 Type 3.1 mill test certificate with chemical analysis, mechanical properties, and heat identification. Dimensional inspection reports and Certificate of Conformance (CoC) are standard. First Article Inspection Reports (FAIR) per AS9102 are available on request for quietrunning submarine propeller.
