Using Ti-511 for marine fastener applications

Titanium offers virtually unsurpassed resistance to crevice, pitting, and s tress-corrosion cracking in seawater environments. Ti-5Al-1Sn-1Zr-1V-0.8Mo (Ti-5111) is a near-alpha titanium alloy of intermediate strength, excellen t toughness, and room-temperature creep resistance designed in a U.S. Navy- sponsored titanium alloy development program for structural submarine appli cations. Ti-5111's desirable mechanical properties nlm excellent corrosion resistance render this titanium alloy an ideal fastener material from both a technical and economic perspective.
