GR12 Titanium Welding Wire

• Breakthrough in Corrosion Resistance:The alloying design containing 0.3% Mo and 0.8% Ni has an annual corrosion rate of less than 0.02mm in hydrochloric acid, chloride, and weak reducing acids. Its resistance to crevice corrosion is superior to pure titanium and close to TA9 (Ti-0.2Pd) alloy. The surface has been acid washed or polished, suitable for harsh scenarios such as seawater desalination equipment and electrolytic cell anode mesh.
• Mechanical performance balance:The tensile strength of the welding wire is ≥ 485MPa, and the weld strength reaches over 90% of the base metal. Through vacuum melting and cold drawing process, the grain size is refined to ASTM grade 8 or above, and the fatigue resistance is excellent.
• Process adaptability:Diameter ranging from 0.1 to 8.0mm, supporting customization of coiled wire (5-20kg) or straight wire (500-1000mm). Welding requires high-purity argon gas (≥ 99.99%) protection to avoid oxidation pollution. The surface can be customized with acid wash or mirror polishing to meet different interface adhesion requirements.

• In the field of chemical engineering, welding of reactor stirring shafts and heat exchanger tube bundles can reduce equipment weight by 40% -60% and maintenance costs by more than 50% by replacing stainless steel.
• Ocean engineering: The sealing reinforcement wire of seawater desalination equipment has better resistance to Cl ⁻ corrosion than 316L stainless steel.
• Electrolytic industry: The anode mesh of the ion membrane electrolytic cell has a corrosion resistance life that is increased by more than three times in high temperature and low pH environments.
