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 <tables id="TABLE-US-00001" num="00001"> <table frame="none" colsep="0" rowsep="0"> <tgroup align="left" colsep="0" rowsep="0" cols="5"> <colspec colname="1" colwidth="42pt" align="center"/> <colspec colname="2" colwidth="35pt" align="center"/> <colspec colname="3" colwidth="49pt" align="center"/> <colspec colname="4" colwidth="49pt" align="center"/> <colspec colname="5" colwidth="42pt" align="center"/> <THEAD> <ROW> <entry namest="1" nameend="5" align="center" rowsep="1"/> </ROW> </THEAD> <TBODY VALIGN="TOP"> <ROW> <ENTRY>C</ENTRY> <ENTRY>Mn</ENTRY> <ENTRY>Si</ENTRY> <ENTRY>P</ENTRY> <ENTRY>S</ENTRY> </ROW> <ROW> <entry namest="1" nameend="5" align="center" rowsep="1"/> </ROW> <ROW> <ENTRY><=0.030</ENTRY> <ENTRY><=2.00</ENTRY> <ENTRY><=0.750</ENTRY> <ENTRY><=0.023</ENTRY> <ENTRY><=0.010</ENTRY> </ROW> <ROW> <entry namest="1" nameend="5" align="center" rowsep="1"/> </ROW> <ROW> <ENTRY>Cr</ENTRY> <ENTRY>Mo</ENTRY> <ENTRY>Ni</ENTRY> <ENTRY>Fe</ENTRY> <ENTRY>"X"</ENTRY> </ROW> <ROW> <entry namest="1" nameend="5" align="center" rowsep="1"/> </ROW> <ROW> <ENTRY>8.5-11.5</ENTRY> <ENTRY>0.0-6.25</ENTRY> <ENTRY>6.5-7.5</ENTRY> <ENTRY>46.185-74.000</ENTRY> <ENTRY>5.0-10.0</ENTRY> </ROW> <ROW> <entry namest="1" nameend="5" align="center" rowsep="1"/> </ROW> </TBODY> </TGROUP> </TABLE> </TABLES> 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.
