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.
