Premium ERTi-7 (ERTi-0.2Pd) Welding Wire: The Ultimate Corrosion-Resistant Solution
TSM Technology Co. is a leading global manufacturer of high-performance titanium grade 7 welding wire. Our ERTi-7 alloys are meticulously engineered with a 0.15% Palladium addition, providing unparalleled resistance to general and localized crevice corrosion in reducing acid environments. When your project demands the metallurgical stability of grade 7 titanium wire, TSM delivers precision-drawn products that exceed AWS A5.16 and ASTM B863 standards.
Introduction to Grade 7 Titanium Welding Rod & Wire
In the world of advanced metallurgy, grade 7 titanium wire (UNS R52400) stands as the gold standard for corrosive environments. This commercially pure titanium is enhanced with approximately 0.12% to 0.25% palladium, a precious metal that significantly boosts the material's resistance to reducing acids, such as hydrochloric, phosphoric, and sulfuric acids.
At TSM Technology Co., our Gr7 titanium wire is manufactured to meet the rigorous demands of the chemical processing, desalination, and power generation industries. Unlike standard Grade 2 wire, the palladium in our ERTi-7 (ERTi-0.2Pd) Welding Rod promotes a highly stable oxide film even in environments with low pH or high chloride levels. This makes it an essential choice for critical welding repairs and new fabrication where crevice corrosion is a primary threat.
Certified Chemical Analysis of ERTi-7 (ERTi-0.2Pd) Welding Wire
The performance of titanium grade 7 welding wire depends entirely on its chemical purity. TSM ensures every batch complies strictly with AWS A5.16 standards.
| Element | Titanium (Ti) | Palladium (Pd) | Iron (Fe) | Oxygen (O) | Carbon (C) | Nitrogen (N) | Hydrogen (H) |
| Content (Wt %) | Balance | 0.12 - 0.25 | ≤ 0.20 | 0.08 - 0.16 | ≤ 0.03 | ≤ 0.015 | ≤ 0.008 |
Mechanical Performance Metrics
hysically, our ERTi-7 (ERTi-0.2Pd) Welding Rod mirrors the strength of Grade 2 but offers the longevity of an alloy. Below are the typical annealed properties.
Tensile Strength
The ultimate strength is approximately 345 MPa (50,000 psi). This ensures robust structural integrity for pressure vessels and piping systems.
Yield Strength
With a 0.2% offset, our wire offers a yield strength of 275 MPa (40,000 psi), providing excellent formability and fabricability.
Elongation
A 20% minimum elongation ensures high ductility, crucial for absorbing stress in complex weld joints.
