Titanium Flange Nuts | High-Strength Corrosion-Resistant Fasteners
Premium Titanium Flange Nuts for Demanding Applications
Our ASTM B348/B381 compliant titanium flange nuts offer unmatched performance in corrosive, high-temperature, and high-strength applications. Manufactured from Grade 2 (CP Titanium), Grade 5 (Ti-6Al-4V), and Grade 7 (Ti-0.2Pd) alloys, these flange nuts provide superior corrosion resistance, lightweight properties, and excellent fatigue life – making them ideal for:
✔ Chemical Processing Plants – Resistant to acids, chlorides, and seawater
✔ Aerospace & Defense – FAA-approved, 40% lighter than steel equivalents
✔ Marine & Offshore – Zero rust in saltwater environments
✔ Medical Implants – Biocompatible (ISO 5832-2 compliant)
✔ Semiconductor Equipment – Ultra-high purity, non-contaminating

Industry Applications (With Case Studies)
Case Study 1: Offshore Oil Platform
Problem: 316SS nuts failed within 6 months in splash zone
Our Solution: Grade 7 titanium flange nuts with 0.2% palladium
Result: No replacements needed after 5+ years (cost savings: $220k)
Case Study 2: Pharmaceutical Reactor
Problem: Stress corrosion cracking in chloride-rich environment
Our Solution: Grade 5 nuts with anodized finish
Result: Eliminated downtime for fastener replacements
FAQ – What Engineers & Buyers Ask
Q: How do titanium flange nuts compare to Inconel?
→ A: 30% lighter with equal corrosion resistance in most media (except extreme oxidizing acids). Cost 20-40% lower.
Q: Can you supply NASA-STD-6012 compliant nuts?
→ A: Yes – Our Grade 5 nuts meet NASA outgassing requirements (TML <1%, CVCM <0.1%).
Q: Do you provide CAD models?
→ A: Downloadable STEP/IGES files available for all standard parts.
