| Characters |
Gr1 titanium offering optimum ductility and cold formability with useful strength, high-
impact toughness, and excellent weldability. Highly corrosion resistant in oxidizing and mildly
reducing environments, including chlorides. |
Grade 2 is the most widely used titanium alloy in all product forms for industrial service,
offering an excellent balance of moderate strength and reasonable ductility. Highly corrosion-
resistant in highly oxidizing and mildly reducing environments, including chlorides. |
Gr5 is the most widely used titanium alloy.It has very high strength but relatively low ductility.The main application of this alloy is in aircraft and spacecraft. Offshore use is growing.The
alloy is weldable and can be precipitation hardened,including chlorides. |
An alpha-beta alloy based on Grade 5. The amount of interstitial elements (O, N, C) is reduced.
Improved stress corrosion cracking (SCC) properties in seawater compared to Grade 5.
Especially suited for thick wall highly stressed parts. |

| Application |
For corrosion resistance in the chemical and marine industries; in airframe construction where
maximum ease of formability is desired. |
For corrosion resistant in the chemical and offshore industries, in aircraft construction where a
certain strength level and ease of formability is desired. Also used in heat exchangers,
hypochlorite systems, fire water systems, ballast water systems, risers, fittings, flanges, fasteners,
forgings, pumps, valves. |
Compressor blades, discs and rings for jet engineers, aircraft components, pressure vessels,
rocket engine cases, offshore pressure vessels. |
Surgical implants, offshore- and seawater applications, high pressur
195 °C. Improved stress corrosion resistance compared to Grade 5. |
