High-Strength Titanium Alloy Gr.12 Rods: Balanced Corrosion Resistance and High Temperature Performance
Titanium Alloy Grade 12 (UNS R53400) rods are a high-performance solution designed for demanding industrial applications. This alloy is a titanium-based material alloyed with 0.3% molybdenum and 0.8% nickel, enhancing its corrosion resistance and mechanical strength. The addition of molybdenum and nickel provides superior resistance to crevice corrosion, particularly in hot chloride and acidic environments, making it suitable for chemical processing, marine, and aerospace industries. Grade 12 titanium rods exhibit excellent weldability and formability, allowing for versatile fabrication processes. They maintain structural integrity at elevated temperatures, with a melting point around 1668°C and a modulus of elasticity of 103 GPa. These properties ensure reliable performance in high-temperature and corrosive conditions.
