Description
Technical Parameters
Introduction
Titanium Grade12 Wire is a near-alpha titanium alloy and it contains with the composition of Ti-0.3Mo-0.8Ni. It is a corrosion-resistant titanium alloy developed in the mid-1970s. It was designed to enhance crevice corrosion resistance in high-temperature brine environments. It is widely used in chemical processing, marine engineering, desalination, oil and gas, and aerospace applications.
Gr12 titanium wire is a corrosion resistant alloy wire, typically produced via a sequence of melting, forging,rolling, multi pass drawing, intermediate annealing, surface treatment, final annealing, and inspection.

Manufacturing Process of Gr12 Titanium Wires
Raw Material & Melting
Melting via VAR or cold-hearth process to produce high-purity Ti 0.3Mo 0.8Ni (Gr12) ingots, with strict control of interstitial elements and ingot inspection.
Ingot Processing
Hot forging and hot rolling into wire rods, followed by annealing and descaling to remove stress and oxide scale
Sequential cold drawing with decreasing die diameters, plus intermediate annealing to counteract work hardening, using dedicated lubrication.
Annealing at 650–750 °C under vacuum or argon to restore ductility and refine grains.
Pickling or bright finishing to achieve the required surface quality, with thorough cleaning.
Supplied in annealed or cold-drawn condition; optional stress-relief annealing.
Straightening and cutting to customer-specified lengths or spooling as coiled wire.
Dimensional, mechanical, chemical, surface, and non-destructive testing to meet ASTM B863 standards.

FAQ
What You Need to Know
Q: What should be noted during welding of Titanium Grade12 Wires?
A: Use high purity argon (≥99.99%) for shielding to prevent oxidation and hydrogen embrittlement.
Clean the weld area thoroughly to remove oil, grease, and moisture.
No preheating or post weld heat treatment is generally required.
Match with Gr12 filler wire for optimal corrosion resistance and mechanical properties.
Q: How to store and handle Titanium Grade12 Wires?
A：Store in a dry, clean, and dust free environment to avoid surface contamination.
Prevent contact with carbon steel, copper, or other metals to avoid galvanic corrosion.
Handle with clean gloves to avoid oil and sweat stains on the surface.
