Corrosion Resistance

The corrosion resistance of Titanium plate and plate products Grade 2/2H (UNS R50400) is the result of a strong, stable, protective oxide film layer that forms when the metal's surface is exposed to oxygen or moisture. The film growth accelerates under strong oxidizing conditions.

The protective film layer of Titanium plate Grade 2/2H (UNS R50400) provides excellent corrosion resistance in many challenging service environments — including oxidizing and organic acids, alkaline solutions, bleaches, wet chlorine, inorganic salts, salt brines, and seawater.

Titanium plate Grade 2/2H (UNS R50400) should not be used in strong reducing acids, anhydrous chlorine, strong caustic solutions, fluorides, or pure oxygen service.

Fabrication Data

Titanium plate Grade 2/2H (UNS R50400) can be easily welded, machined, and hot and cold worked by standard shop fabrication practices.

Hot Forming

Hot forming operations should be performed in the temperature range between 400 and 600°F (204 and 316°C). Care must be taken to prevent the formation of excessive alpha case which should be removed after processing.

Cold Forming

Titanium plate and plate products Grade 2/2H (UNS R50400) can be worked by any conventional cold-forming method at room temperature. Three factors make titanium somewhat different from other metals.

  • Room temperature ductility less than other materials may require more generous bend radii and lower stretch formability
  • Modulus of elasticity is about half that of steel which can cause spring back after forming
  • Galling tendency is greater than stainless steel which calls for close attention to lubrication in any forming operation in which titanium is in contact with metal dies or forming equipment


Titanium plate Grade 2/2H (UNS R50400) can be joined by a variety of welding procedures using titanium filler metal. Gas tungsten arc welding (GTAW) is the most common welding process for Titanium plate Grade 2/2H (UNS R50400), but plasma arc welding, spot welding, electron beam, laser beam, resistance welding, and diffusion welding can all be utilized. For whichever process that is selected, inert gas shielding techniques must be employed to prevent oxygen pickup and embrittlement in the weld area.


Titanium plate’s Grade 2/2H (UNS R50400) machining characteristics are similar to those of austenitic stainless steels. Low cutting speeds, heavy feed rates, and a heavy dosage of cutting fluids are recommended. Sharp cutting tools and rigid setups are suggested. Given titanium’s tendency to gall, the feeding should never be stopped while the tool and piece are in moving contact. Titanium chips are highly combustible, and precautions should be taken to avoid fire hazards.

Applications suggested for the materials are described only to help readers make their own evaluations and decisions, and are neither guarantees nor to be construed as express or implied warranties of suitability for these or other applications. Stainless Steel, Nickel Alloy and Titanium products are classified as sheet if the thickness of the metals is less than 3/16” (4.7mm). If the thickness of the metal is 3/16” (4.7mm) or more, then it is considered a plate.
