A golf club head is described which has a body that is formed at least in part from a stainless steel alloy having the following composition in weight percent: <tables id="TABLE-US-00001" num="00001"> <table frame="none" colsep="0" rowsep="0"> <tgroup align="left" colsep="0" rowsep="0" cols="3"> <colspec colname="offset" colwidth="42pt" align="left"/> <colspec colname="1" colwidth="42pt" align="left"/> <colspec colname="2" colwidth="133pt" align="center"/> <thead> <row> <entry/> <entry namest="offset" nameend="2" align="center" rowsep="1"/> </row> </thead> <tbody valign="top"> <row> <entry/> <entry>Carbon</entry> <entry>0.25 max.</entry> </row> <row> <entry/> <entry>Manganese</entry> <entry>14-20</entry> </row> <row> <entry/> <entry>Silicon</entry> <entry>up to 2.0</entry> </row> <row> <entry/> <entry>Phosphorus</entry> <entry>0.05 max.</entry> </row> <row> <entry/> <entry>Sulfur</entry> <entry> 0.5 max.</entry> </row> <row> <entry/> <entry>Chromium</entry> <entry>12-22</entry> </row> <row> <entry/> <entry>Nickel</entry> <entry> 3.5 max.</entry> </row> <row> <entry/> <entry>Molybdenum</entry> <entry>0.5-4 </entry> </row> <row> <entry/> <entry>Copper</entry> <entry> 2.0 max.</entry> </row> <row> <entry/> <entry>Nitrogen</entry> <entry>0.2-0.8</entry> </row> <row> <entry/> <entry>Boron</entry> <entry>0.06 max.</entry> </row> <row> <entry/> <entry namest="offset" nameend="2" align="center" rowsep="1"/> </row> </tbody> </tgroup> </table> </tables> The balance of the alloy is iron and the usual impurities. The stainless steel alloy provides a hardness of about 80 HRB up to about 25 HRC. The golf club head provides a unique combination of high strength and hardness, good ductility, excellent "feel", and good durability. A method of making the disclosed golf club head is also described.
