UNS R30008 is a wrought 40cobalt-20chromium-16iron-15nickel-7molybdenum alloy delivered in the form of wire and strip used for the manufacture of surgical implants.
UNS R30008 provides the best solution whenever high mechanical performance is required under severely corrosive service conditions.The mechanical strength increases with cold rolling strain. Yield strengths higher than 1800 MPa can be achieved simply by cold working. Additional strengthening can be obtained by age hardening at 500°C. The influence of aging is negligible in the annealed condition, but increases with the degree of cold work. By combining an appropriate amount of cold work with aging, it is possible to adjust the mechanical properties.

Characters
- Exceptional resistance to corrosion, stress corrosion cracking and hydrogen embrtittlement.
- Good fatigue stregth.
- The absence of aging in service.
- The absence of magnetism.
- Ability to be used over a wide range of temperatures, from liquid helium to about 500°C.
- Perfect passivity in contact with human tissues.
- The possibility of increasing the strength of parts by age hardening after forming, leading to strength levels unattainable with other materials.
- The absence of brittleness at low temperatures (no transition temperature).
- A maximum service temperature about 100°C higher than for stainless steels.
- A corrosion resistance vastly superior to that of molybdenum containing stainless steels.
- A very high yield strength that combined with a high elastic modulus in both tension and torsion, enables the storage and rapid release of large amounts of elastic energy.
