Gr.7 Strips are palladium-enhanced titanium alloy strips designed to deliver superior corrosion resistance in highly aggressive chemical environments, especially where reducing acids and chloride media are present. Compared with commercially pure titanium, the addition of palladium (0.12–0.25%) significantly improves resistance to crevice corrosion, pitting, and acid attack, particularly in hydrochloric and sulfuric systems. This makes Gr.7 Strips a preferred material for long-term service in critical process equipment where reliability and lifecycle performance are essential.
From a mechanical standpoint, Gr.7 Strips maintain a balanced combination of moderate strength and excellent ductility, with tensile strength ranging from 345 MPa to 515 MPa and elongation above 15%, ensuring stable forming and fabrication performance. The alloy retains its corrosion resistance even after welding or cold forming, without requiring complex heat treatment, which simplifies manufacturing and reduces operational costs.
In regions such as Southeast Asia, the Middle East, Europe, and the Americas—where chemical processing, marine engineering, and energy industries operate under highly corrosive conditions—Gr.7 Strips provide a dependable solution. With a density of only 4.51 g/cm³, they also contribute to weight reduction in structural and transport systems. Conformance to ASTM B265, ASME SB265, and EN standards ensures consistency, traceability, and global engineering acceptance.

Gr.7 Strips are widely used in demanding environments where corrosion resistance is critical:
1. Why choose Gr.7 Strips instead of pure titanium?
Gr.7 Strips contain palladium, which significantly enhances resistance to reducing acids and improves performance in highly corrosive chemical environments compared to standard titanium grades.
2. Are Gr.7 Strips suitable for marine environments?
Yes, they offer excellent resistance to seawater corrosion, including pitting and crevice corrosion, making them ideal for offshore and desalination systems.
3. Can Gr.7 Strips be welded and formed easily?
Gr.7 Strips maintain excellent weldability and cold formability, similar to commercially pure titanium, without requiring post-weld heat treatment.
