Annotation of standard text ASTM F90-23 :

This specification covers the chemical, mechanical, and metallurgical requirements for wrought cobalt-20chromium-15tungsten-10nickel alloy bars, rods, wires, sheets, and strips (except surgical fixation wires) for use in surgical implants. All alloys shall be furnished to the purchaser´s specifications, in the annealed or cold-worked condition. Then, bars and wires shall be finished bright annealed, cold drawn, pickled, ground, or ground and polished, as specified by the purchaser. While, sheets shall be furnished bright annealed, pickled, cold-rolled, or polished, as specified by the purchaser. The alloys shall adhere to specified values of ultimate tensile strength, yield strength, elongation, and microcleanliness.

Additional information

1. Scope

1.1?This specification covers the chemical, mechanical, and metallurgical requirements for wrought cobalt-20chromium-15tungsten-10nickel alloy used for surgical implants. The properties specified apply specifically to wrought bar, rod, wire, sheet, and strip, but do not apply to surgical fixation wire (see Specification F1091).

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, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

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.
