Gr4 Titanium Bar

Gr4 titanium bar is a pure titanium material, with medium strength products, it has excellent corrosion resistance, weldability, strength, ductility, and formability. The manufacturing process is radial forging, with a good surface, straightness, and roundness in the final products.

 

Gr4 titanium rod has the highest strength among the pure titanium material due to its high oxygen and extra-high strength. Gr4 titanium rod combines excellent corrosion resistance with good formability and weldability. Titanium bar Gr4 is mainly used in hydraulic and instrumentation tubing. Generally chosen for its corrosion resistance in chemical engineering equipment, marine, and airframe parts. It can be used for parts in an environment of 400 ° F and oxidation resistance to 600 ° F.

Gr4 titanium alloy is a kind of α-type titanium alloy. This kind of alloy is the α-type single phase at room temperature. It cannot be hardened by heat treatment but mainly depends on solution strengthening.

 

The strength at room temperature is generally lower than that of β '> type and α+β type titanium alloys, while the strength and creep strength at high temperature (500-600℃) are the highest among the three types of titanium alloys. The structure is stable, oxidation resistance and welding performance are good, and corrosion resistance and machinable performance are also good, Gr4 is one of the excellent ultra-low temperature alloys.

 

Acid and alkali corrosion resistance, seawater corrosion resistance, and sewage corrosion resistance.

 

With density (4.51), Gr4 is a lightweight material.

 

Applications between -253° and 600°, its tensile strength is almost the highest among metals.

With properties and applications of titanium alloy

 

Compared with other titanium alloys, such as α + β alloy, its strength is lower and cannot be strengthened by heat treatment. Its main characteristics are good high-temperature performance, stable structure, good welding, corrosion resistance, and thermal stability. Its disadvantage is poor plasticity in hot working. Nearly α titanium alloy is the basis for the development of heat-resistant titanium alloy and is the direction of the development of high-temperature titanium alloy in recent years. BT20 (TA15) is the most widely used titanium alloy in aircraft, which is mainly used to make the wall plate, frame, beam, and structural parts of aircraft. Near α titanium alloy can also be used in the fabrication of aircraft skin, engine blades and disks, ultra-low temperature containers, and space vehicle fuel storage.
