NXF TC4/Ti-6Al-4V M1-100 Grade 4-10 ANSI/ASME B18.2.2 Surface Colour Cold Form Titanium Alloy Flange Nut
TC4 Introduction
Titanium Alloy Flange Nut Introduction
1.We have our own factory, and we can control the cost by producing by ourselves. We have a great advantage in price and can give you the lowest price.
2. We can strictly control the quality. We have production, quality inspection, warehousing and other departments to coordinate and control the quality.
3.Our biggest advantage is 3S service. Small quantity, short time, special materials.
4.We have excellent quality certificate system and trademark certificate.
1. Raw Material Preparation
Select qualified titanium alloy ingots: Ti-6Al-4V (Grade 5), Ti Grade 2, etc.Inspect chemical composition, mechanical properties, and certificate.Cut into proper bars or billets according to nut size.
2. Hot Forging / Cold Heading
Hot forging: Heat billets to 900–1100 °C, press-form into flange nut preform.Cold heading: For small sizes, high-speed forming for better dimensional accuracy.Form integrated hex body and flange in one step.
3. Annealing Heat Treatment
Heat at 700–800 °C for stress relief and softening.Improve machinability and mechanical performance.Cool in furnace or air to avoid internal stress.
4. Turning & CNC Machining
Machine outer hex, flange surface, chamfer, and overall dimension.Ensure flatness, perpendicularity, and surface roughness.
5. Tapping (Thread Processing)
Use high-precision taps to process internal threads.Strictly control thread tolerance: 6H, ISO 68‑1, DIN 6921.Prevent galling during titanium thread machining.
6. Surface Treatment
Deburring, sandblasting, polishing.Anodizing (coloring), passivation, or coating for anti‑galling & anti‑corrosion.
7. Hardness & Performance Testing
Hardness test: HRC, HV.Tensile strength, proof load, fatigue test.Dimensional inspection: caliper, gauge, CMM.
8. Anti‑galling Treatment & Lubrication
Apply anti‑galling compound or lubricant coating.Reduce friction and prevent seizing during assembly.
9. Final Inspection & Sorting
100% visual and dimensional check.Sort by size, grade, surface finish.Eliminate defective products.
10. Packaging & Warehousing
Clean, oiled, vacuum or box packaging.Label: grade, size, quantity, material certificate.Store in dry, anti‑humidity environment.
