Biodur® 108

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