Identical with ASTM B348, ASME SB-348 is the standard specification for titanium and titanium alloy bars and billets. This specification covers all annealed grades of titanium and titanium alloy. Titanium bars can be hot rolled, forged, extruded, or cold worked with a cross sectional area of ≤ 16 inch^2. Rectangular bars must be ≤ 10 inch in width and > 4.8 mm in thickness. Titanium billets can be hot worked or forged from an ingot, with a cross sectional area > 16 inch²Ìýwhose width is less than 5 times its thickness.

The standard specification also covers referenced documents, chemical composition, mechanical properties, dimensions, weight, permissible variations, workmanship, finish, appearance, test & inspection, and packing information for titanium and titanium alloy bars and billets.
