Ti-5Al- 1Sn- lZr- lV-0.8M0 is a near alpha titanium alloy of intermediate strength, designed for high toughness, good weldability, stress-corrosion cracking resistance, and room temperature creep resistance. Ideally suited for marine environments, Ti 5111 offers the means to aid the navy in fulfilling their goals of reducing maintenance and life cycle costs,
reducing topside and overall weight, improve survivability and increase reliability. The alloy was recently included in the ASTM bar and plate specifications as ASTM Grade 32.
