Abstract
In the paper are illustrated the results of an extensive investigation performed by a research working group constituted by nine laboratories, with the target to study a material alternative to the traditional ASTM F138 austenitic stainless steel. In particular a 25Cr-7Ni-4Mo-0.28N austeno-ferritic duplex stainless steel, with high molybdenum and nitrogen contents, was developed. All the in vitro, in vivo on animals, and clinical results obtained tilt now have shown that the proposed steel can be suggested as a convenient substitute for the ASTM F138 steel because it is not susceptible to crevice corrosion in the human body and has better mechanical properties (in particular better fatigue resistance) than the traditional one.Pubblicazioni consigliate
