Standard Specification for Unalloyed Titanium, for Surgical Implant Applications (UNS R50250, UNS R50400, UNS R50550, UNS R50700)

ABSTRACT
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.
SCOPE
1.1 This specification covers the chemical, mechanical, and metallurgical requirements for four grades of unalloyed titanium strip, sheet, plate, bar, billet, forging, and wire used for the manufacture of surgical implants.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
