Providing High-quality Grade 7 Titanium Plate to Serve Customers Worldwide
Grade 7 titanium plate (Ti Grade 7 / UNS R52400) is a palladium-enhanced, commercially pure (CP) titanium alloy specifically engineered for supreme corrosion resistance in aggressive environments. It consists of titanium (≥99%) with a critical addition of 0.12–0.25% palladium (Pd), which fundamentally alters its electrochemical behavior. This palladium modification dramatically improves resistance to reducing acids (e.g., sulfuric, hydrochloric, phosphoric), chloride solutions (including seawater and brines), and crevice/pitting corrosion—scenarios where standard CP grades like Grade 2 would rapidly degrade. While retaining the inherent advantages of titanium—low density (~4.5 g/cm³), high strength-to-weight ratio, excellent weldability, and biocompatibility—Grade 7 exhibits superior performance at elevated temperatures (up to ~400°C/750°F) and in highly oxidizing or acidic conditions. Its passive oxide layer, stabilized by palladium, provides unparalleled protection against chemical attack, making it one of the most corrosion-resistant metallic materials available.
Where is Grade 7 titanium plate used?
Grade 7 titanium plate is extensively used in chemical processing for critical components like reactor vessels, heat exchangers, piping systems, and agitators handling acids, chlorides, or organic solvents. In marine and offshore engineering, it serves in seawater desalination plants, heat rejection systems, and subsea equipment exposed to high-salinity environments. The alloy also excels in pollution control systems (e.g., flue-gas desulfurization scrubbers), pharmaceutical manufacturing, and medical implants (e.g., orthopedic devices) due to its inertness and longevity. Despite its higher initial cost—driven by palladium content—Grade 7 delivers exceptional lifecycle value by minimizing downtime, maintenance, and replacement costs in corrosive service. Its reliability in preventing catastrophic failures ensures safety and efficiency in applications ranging from nuclear waste containment to aerospace fluid systems, justifying its selection as a premium solution for the most demanding corrosion challenges.

Key Characteristics
- Strength-to-Weight Ratio: Comparable to pure titanium (Grades 1–4) but lower than Ti-6Al-4V (Grade 5) or Ti-3Al-2.5V (Grade 9). Optimized for corrosion resistance over mechanical strength.
- Corrosion Resistance: Unmatched in reducing acids (e.g., HCl, H₂SO₄), chlorides, and crevice corrosion environments. Outperforms all commercially pure grades (1–4) and Grade 5/9 in aggressive chemical media due to palladium (Pd) stabilization.
- Biocompatibility: Fully non-toxic and MRI-compatible. Suitable for surgical instruments and chemical processing equipment, though not used for permanent implants (Grade 23 preferred).
- Formability: Retains excellent cold formability, weldability, and machinability of pure titanium. Significantly easier to fabricate than Grade 5/9, enabling complex geometries without specialized tooling.

Grade 7 titanium plate is a commercially pure titanium alloy with the addition of 0.12-0.25% palladium, which significantly enhances its corrosion resistance. This combination maintains the excellent formability and weldability of pure titanium while providing superior resistance to reducing acids and other highly corrosive environments.
Grade 7 titanium plates offer good strength with a minimum yield strength of 275 MPa and minimum tensile strength of 485 MPa. They maintain excellent ductility with approximately 20% elongation, allowing for good formability during fabrication processes.
Yes, Grade 7 titanium plates can be welded using standard titanium welding procedures including TIG, MIG, and plasma arc welding. However, proper shielding with inert gas is essential to prevent contamination during welding. The palladium addition does not significantly affect weldability compared to other commercially pure titanium grades.
