DETAILED INFORMATION
Titanium Plate Grade 2 is commercially pure (99% minimum). Chemical composition of Grade 2 affects mechanical properties and design capability. All four grades have similar corrosion resistance. Titanium has higher corrosion resistance than stainless steel, and is exceptionally light weight. Among the four commercially pure (C.P.) Titanium Plate Grade 2 is the alloy of choice for most industrial applications that require ductility and corrosion resistance.
The lower density of Titanium Plate Grade 2 makes it very desirable where weight is a concern. Titanium alloys are used primarily in the medical and aerospace industries. Furthermore, titanium Grade 2 is well suited to applications in the marine, chemical processing, and desalination industries due to its strength and corrosion resistance.
General Properties
Titanium Plate and Plate Products with Excellent Corrosion Resistant Strength and Ductility.
This is Titanium Plate Grade 2 (UNS R50400). This titanium grade offers excellent strength and ductility with outstanding corrosion resistance in highly oxidizing and mildly reducing environments.
The strength of Titanium Grade 2 (UNS R50400) is slightly lower than that of Titanium Grade 3 (UNS R50550), but it is stronger than Titanium Grade 1 (UNS R50250). A minimum yield strength of 40 ksi (275 MPa) is guaranteed. Compared to other commercially pure plate grades, it has the same corrosion resistance.
The titanium plate Grade 2 (UNS R50400) can be operated continuously at 800°F (425°C) and intermittently at 1000°F (540°C).
By standard fabrication practices, Titanium Plate Grade 2 (UNS R50400) can be easily welded, machined, and hot and cold worked.
Thicknesses
Our inventory of stainless steel and nickel alloy plates includes titanium plate Grade 2/2H (UNS R50400). With over 18 million pounds of specialty plate in stock, we maintain the largest inventory in North America! The thicknesses of titanium plate and plate products Grade 2/2H (UNS R50400) range from .1875″ (4.8mm) through 3.5″ (88.9mm).
Resistance to Corrosion
In titanium’s grades, corrosion resistance is provided by a highly adherent, stable, protective oxide film. Commercially pure titanium grades are resistant to most oxidizing, neutral, and inhibited reducing environments, as well as mildly reducing environments. Seawater and marine atmospheric corrosion are not a problem for grade 2. Corrosion resistance is similar between the four types, but mechanical properties and oxygen and iron contents vary. Titanium Plate Grade 2 is resistant to moist chlorides and metallic chlorides, chlorite and hypochlorite solutions, nitric and chromic acids, organic acids, and many gaseous industrial solvents.
Fabrication and Heat Treatment
Due to its good ductility, Titanium Plate Grade 2 is capable of being cold formed. Material under 0.070 inches thick should have a minimum bend radius of 2T, while material over 0.070 inches thick should have a minimum bend radius of 2.5T. Material can also be machined, hot worked, and welded. Working at high temperatures should be done between 400°F and 600°F. During stress relief, the temperature should be raised between 900°F and 1100°F, followed by forced air or slow cooling. There is an annealing temperature range of 1200°F to 1400°F for 6 minutes to 2 hours, followed by an air cooling period.
MIG and TIG welding can be used to weld Grade 2 titanium. To prevent oxygen pickup and embrittlement of the weld area, inert gas shielding is crucial. Welding procedures should be tested before accepting argon and helium mixtures. There is no need for preheating or postheating.

Corrosion Resistance
The corrosion resistance of Titanium plate and plate products Grade 2 (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 (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 (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 (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 (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
Welding
Titanium plate Grade 2 (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 (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.
Machining
Titanium plate’s Grade 2 (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.
