Project Description
Product Description
Titanium Grade 7 (UNS R52400, 3.7235) is a palladium-enhanced titanium alloy offering exceptional corrosion resistance. This nickel-free alloy contains 0.12-0.25% palladium within a commercially pure titanium base, making it ideal for harsh chemical processing, marine engineering, and pharmaceutical applications where superior crevice corrosion resistance is critical.
Applications
Our Grade 7 titanium pipes are specifically engineered for:
– Chemical processing equipment (heat exchangers, reactors)
– Offshore oil & gas piping systems
– Desalination plant condenser tubes
– Pharmaceutical manufacturing components
– Acid production and handling systems

Grade 7 titanium tube data
Grade 7 is the grade to quote when the duty is reducing-acid service, crevice-corrosion duty in chemical and pharmaceutical plant. The mechanical values above are the ASTM B338 minima, so a mill certificate that meets them can be released against either the tube or the pipe specification depending on the product form ordered.

Titanium is priced per kilogram but sold per metre, and the two do not track each other when the wall changes. Send OD × wall, length and the test standard, and the offer will state both the theoretical weight per metre and the price basis so the two can be compared across suppliers.
