CarTech BioDur 108 alloy is an essentially nickel-free austenitic stainless alloy. The alloy contains a high nitrogen content to maintain its austenitic structure. As a result, CarTech BioDur 108 alloy has improved levels of tensile and fatigue strength, as compared to nickel-containing alloys such as 316L (ASTM F138), 22Cr-13Ni-5Mn (ASTM F1314), and 734 alloy (ASTM F1586). The resistance of CarTech BioDur 108 alloy to pitting and crevice corrosion is superior to 316L alloy and equivalent to the 22Cr-13Ni-5Mn alloy and 734 alloys. CarTech BioDur 108 alloy is produced by the Electro-Slag Remelting (ESR) process to assure its microstructural integrity and cleanness. The alloy is non-magnetic and essentially free of ferrite phase.

Applications:
CarTech BioDur 108 alloy should be considered for use in applications requiring high levels of strength and corrosion resistance. This alloy should be considered a potential candidate for implantable orthopedic applications such as bone plates, bone screws, spinal fixation components, hip and knee components, hypoallergenic jewelry, orthodonic appliances, and other medical components and instruments fabricated by forging and machining.
