This specification covers the chemical, mechanical, and metallurgical requirements for four grades of unalloyed titanium strips, sheets, plates, bars, billets, forgings, and wires used for the manufacture of surgical implants. The four grades identified here are defined as follows: Grade 1-UNS R50250; Grade 2-UNS R50400; Grade 3-UNS R50550; and Grade 4-UNS R50700. Mill products may be supplied with a descaled or pickled, abrasive blasted, chemically milled, ground, machined, peeled, or polished finish, or as specified by the purchaser. Materials shall be furnished in the hotworked, cold-worked, forged, annealed, or stress-relieved condition. Mechanical properties to which the titanium materials shall conform are ultimate tensile strength, yield strength, elongation, and reduction of area.

Production
Condition - Material shall be supplied in the hot rolled, cold worked, forged, annealed or stress relieved condition.
Surface Finish - Unalloyed titanium material shall be free from harmful external and internal defects of a nature to interfere with its intended purpose.
Material may be furnished in the form of descaling, pickling, sandblasting, grinding, or a combination of these operations. If spot grinding does not reduce dimensions below the minimum allowed by the dimensional tolerances ordered, the manufacturer shall be permitted to remove smaller surface defects by spot grinding.
