Grade 2 Titanium Seamless Pipe Manufacturing Process

Grade 2 Titanium Welded Pipe Manufacturing Process

Daxun's ASTM B338 Grade 2 titanium welded pipe is meticulously crafted from annealed flat-rolled steel plates or steel strips using an advanced automatic arc welding (TIG) process. The comprehensive production sequence encompasses: titanium plate uncoiling, shearing, butt welding, cleaning, pipe forming, TIG welding, eddy current testing, pre-sizing, annealing, precision reducing and sizing, straightening, eddy current testing, caliper marking, cutting, ultrasonic testing, hydrostatic testing, final inspection, and packaging. Each welded pipe undergoes at least one stress relief heat treatment post-forming and welding to ensure optimal performance. Note that Daxun does not incorporate any filler materials during the welding process, maintaining the integrity and quality of the pipes.

Ti-6Al-4V Titanium Pipe - Grade 5 Titanium Tube

Titanium Alloy - (UNS R56400)
Introduction
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 (UNS R56400) stands as the most renowned titanium alloy. This duplex alpha+beta titanium alloy is stabilized by aluminum for the alpha phase and vanadium for the beta phase. It boasts remarkable strength and can perform efficiently even at low temperatures around 800°F (427°C). Renowned for its versatility, ATI Ti-6Al-4V, Grade 5 alloy is ideal for annealing, solution treating, and aging. Its applications include compressor blades, disks, and rings for jet engines, components for fuselages and space capsules, pressure vessels, *** cases, helicopter rotor hubs, fasteners, and other critical forgings that benefit from a high strength-to-weight ratio.
The alloy's initial melting process employs vacuum arc (VAR), electron beam (EB), or plasma arc hearth melting (PAM) techniques, with subsequent remelting carried out in one or two vacuum arc steps to ensure purity and consistency.

Heat Treatment

Annealed at 1,700-1,900°F (927 - 1,038°C) to achieve high hardness, tensile strength, and fatigue strength.
DAXUN 6-4 Grade 5 Titanium Tube can undergo various heat treatments to meet specific requirements.
1. Annealing: 1,275 - 1,400°F (691 - 760°C) for ½ to 2 hours, then air or furnace cooling.
2. Stress Relief Annealing: 1,000 - 1,200°F (538 - 649°C) for 1 to 8 hours, followed by air or furnace cooling.
3. Solution Heat Treating: 1,675 - 1,750°F (913 - 954°C) for 1 hour, then water quenching.
4. Aging: 975 - 1,025°F (524 - 552°C) for 4 to 8 hours, followed by air cooling.

Optimum Properties

Small cross-sections quenched rapidly in the solution treated and aged condition exhibit optimal properties. Larger cross-sections or delayed quenching may yield less than optimal results.

Hardness

In the annealed state, the typical hardness is Rockwell C 30-34, while in the solution treated and aged state, it is approximately Rockwell C 35-39.

Forgeability/Formability

Experience unparalleled performance with DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube. Expertly forged at a heat of 1,750°F (954°C) with a final touch at 1,450°F (788°C), we recommend a reduction of at least 35% for superior results. Achieve the pinnacle of strength and reliability with our high-strength, medical-grade titanium tube.

DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube is engineered for toughness, even at room temperature. Despite its formidable nature, when expertly annealed, it can undergo severe forming operations like bending and stretching at temperatures up to 1,200°F (649°C) without compromising its mechanical prowess. For precision hot sizing or forming, employ creep forming between 1,000 and 1,200°F (538 to 649°C) to maintain integrity.

Machinability

Achieve precision with DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube, machinable using advanced methods akin to austenitic stainless steels. Ensure optimal performance by employing slow speeds, high feeds, and robust tool rigidity, alongside generous applications of non-chlorinated cutting fluids.

Weldability

DAXUN Ti-6Al-4V Titanium Tube Grade 5 Titanium Tube showcases superior weldability in both annealed and solution-partially aged states. Post-weld heat treatments perfect the aging process.

During welding, it is crucial to prevent contamination from oxygen, nitrogen, and hydrogen. Utilize fusion welding in an inert gas-filled chamber or employ an inert gas tail shield over the molten metal and adjacent hot zones. Spot welding, seam welding, and flash welding can be performed effectively without protective atmospheres.

Special Considerations

DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube requires careful handling to avoid hydrogen contamination during improper pickling, and the absorption of oxygen, nitrogen, and carbon during forging, heat treating, and brazing. Such contamination can significantly reduce ductility and impair notch sensitivity and formability, necessitating stringent quality controls.
