Abstract

This specification establishes the chemical, mechanical, and metallurgical requirements for wrought molybdenum-47.5 rhenium alloy to be used in the manufacture of surgical implants. The alloy consists of nominal 47.5 mass percent rhenium balance molybdenum of approximately 99.79% purity and residual plus trace elements. This specification applies to round bars and flats from 1.00 mm (0.0394 in.) to 101.60 mm (4.00 in.) in diameter or thickness (other sizes and shapes by special order), any sheet under 4.76 mm (0.1875 in.) in thickness and 610 mm (24 in.) or more in width, and other forms and shapes as may be agreed upon by the purchaser and supplier. The product may be furnished to the implant manufacturer as mechanically or chemically descaled by pickling, abrasively blasting, chemically milled, ground, machined, peeled, polished, combinations of these operations, or as specified by the purchaser. On billets, bars, plates, and forgings, minor surface imperfections may be removed by grinding or machining if the resultant area meets the dimensional and surface finish requirements of this specification.

Also covered by this specification are ordering information, ultrasonic inspection, significance of numerical limits, certification, and quality program requirements.

Scope

1.1 This specification covers the chemical, mechanical, and metallurgical requirements for wrought molybdenum-47.5 rhenium alloy to be used in the manufacture of surgical implants.

1.2 The SI units in this standard are the primary units. The values stated in either primary SI units or secondary 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 nonconformance with the standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 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.
