Q: How does Monel K500 Compared to Titanium Grade 5?
A: Both Monel bolts and titanium bolts offer excellent resistance to saltwater conditions. Titanium has just a slight edge on corrosion resistance to stagnant seawater compared to Monel – but this is minuscule.
The main differences are strength and applications. In terms of strength, Monel K500 will offer about 160ksi of tensile strength compared to Titanium grade 5 bolts 148ksi. – slightly higher. Monel K500 bolts are also more commonly used by the military for saltwater conditions and can be quoted per MIL Spec.
In comparison, Titanium grade 5 per spec TI 6AL-4V can be used in medical
applications for inertness, biocompatibility and strength.
