STANDARD published on 1.5.2023
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification covers the requirements for unfinished cobalt-28chromium-6molybdenum (UNS R30075) investment product alloy castings for surgical implant applications, and casting alloys of the same in the form of shot, bar, or ingots to be used in the manufacture of surgical implants. This specification does not apply to completed surgical implants made from castings. Both product castings and casting alloys shall conform to specified chemical composition and mechanical requirements including ultimate tensile strength, yield strength, elongation, and reduction of area. Product castings shall additional undergo liquid penetrant, radiographic, metallographic, and hardness examination.
