Standard Specification for Wrought Cobalt-20Chromium-15Tungsten-10Nickel Alloy for Surgical Implant Applications (UNS R30605)
ABSTRACT
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.
SCOPE
1.1 This specification covers the 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 F 1091).
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
