Engineered to Outperform in the Most Demanding Environments
Where standard titanium and stainless steel fail, Grade 7 (Ti-0.15Pd) screws and nuts deliver unmatched corrosion resistance-thanks to their palladium-enhanced chemistry. Designed for industries battling aggressive acids, saltwater, and chlorine exposure, these fasteners ensure long-term reliability where others corrode.
Why Grade 7 Titanium Stands Above the Rest
✅ Elite Corrosion Resistance
Unaffected by boiling hydrochloric/sulfuric acid, seawater, and hypochlorite solutions
Palladium (Pd) reinforcement prevents pitting and crevice corrosion
✅ Dual-Purpose Performance
Industrial: ASTM B348 compliant for chemical plants, offshore rigs, and desalination systems
Medical: ASTM F2885 compliant for surgical instruments and implant assembly
✅ Lightweight & Strong
40% lighter than steel with comparable strength (345-483 MPa)
Non-magnetic & MRI-safe-ideal for sensitive electronics and medical devices
✅ Precision-Engineered Options
Threads: M1.6 to M24 (Class 6g/6H)
Coatings: Xylan® or Teflon® for added chemical resistance
Surface Finishes: Mill, polished, or passivated (medical-grade)
Proven Performance: Industry-Leading Durability
| Test Condition | Grade 7 Titanium | 316 Stainless Steel | Grade 2 Titanium |
|---|---|---|---|
| 5% HCl @ 50°C (1000h) | 0.001 mm/y | 25+ mm/y (Fails) | 0.5 mm/y |
| Salt Fog (ASTM B117, 3000h) | No Effect | Severe Pitting | Slight Discoloration |
| Chlorine Gas Exposure | No Corrosion | Rapid Degradation | Moderate Pitting |
