Grade 9 titanium tube data
Grade 9 is the grade to quote when the duty is high-strength hydraulic and instrument tubing, aerospace and subsea control lines. 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.
