Materials

Titanium Grade 2 (UNS R50400)

• Material: Commercially pure titanium (unalloyed), known for its excellent corrosion resistance and high strength-to-weight ratio.

• Mechanical Properties:

  • Moderate strength: ~50 ksi yield strength (lower than Ti-6Al-4V, but stronger than many steels when weight-adjusted).

  • Excellent ductility and toughness.

  • Density is ~45% that of steel, making it extremely lightweight.

  • Retains useful strength up to ~600°F (315°C).

• Corrosion Resistance:

  • Exceptional resistance to oxidation, seawater, and chlorides.

  • Excellent performance in oxidizing, neutral, and mildly reducing environments.

  • Resistant to many acids (nitric, chromic) but not ideal in strong reducing acids (like hydrofluoric or hydrochloric).

  • Naturally forms a protective oxide film, making it a preferred choice for marine and chemical service fasteners.

• Manufacturing Considerations:

  • Readily formable and weldable compared to higher-strength titanium alloys.

  • Machinability is fair—requires sharp tooling and slow speeds due to work hardening and low thermal conductivity.

  • Typically supplied in annealed condition for fastener manufacturing.

• Applications in Fasteners & Components:

  • Marine fasteners (bolts, nuts, studs) where seawater resistance is critical.

  • Chemical processing equipment fasteners exposed to oxidizing or chloride-containing environments.

  • Aerospace and defense hardware where lightweight, corrosion-resistant fastening is needed.

  • Medical implants and equipment where biocompatibility is beneficial.
