Project Description
Product Description
Titanium Grade 11 (UNS R52250, 3.7225) is a palladium-modified commercially pure titanium with 0.12-0.25% palladium content. This enhanced corrosion-resistant alloy maintains excellent formability while providing superior performance in acidic and chloride-rich environments, widely used in chemical processing, marine engineering, and power generation industries.

Grade 11 titanium tube data
Grade 11 is the grade to quote when the duty is welded and seamless tubing in mildly reducing acid and chloride service, FGD and hydrometallurgy. 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.
