  • Stainless steel alloy having lowered nickel-chrominum toxicity and improved biocompatibility
    Patent number: 8580189
    Abstract: The present invention is directed towards an austenitic, stainless steel series 300 alloy having improved biocompatible characteristics. The modified stainless steel alloy consists essentially of, in weight percent, about C Mn Si P S ?0.030 ?2.00 ?0.750 ?0.023 ?0.010 Cr Mo Ni Fe “X” 8.5-11.5 0.0-6.25 6.5-7.5 46.185-74.000 5.0-10.0 whereby variable “X” could be comprised from a group consisting of Gold, Osmium, Palladium, Platinum, Rhenium, Tantalum, or Tungsten. The alloy provides a unique combination of strength, ductility, corrosion resistance, and other mechanical properties which also has improved biocompatible characteristics.
