Abstract
This specification covers the chemical composition and mechanical requirements for 35cobalt-35nickel-20chromium-10molybdenum alloy (UNS R30035) forgings for use in surgical implants. The material covered here shall be in the form of bars, plates, sheets, or wires manufactured in the solution-annealed condition with a finish suitable for forging by hammering, pressing, rolling, extruding, or upsetting.
