    Fatigue Properties of 1.6582 (AISI 4140 V.S 1.6582)

    HI I'm looking for a material to substitute our 4140 shafts. These shafts are working with 12000 rpm. Now we use of 4140 (quenched and tempered). Is it possible to use 1.6582 instead of 4140??? Is Fatigue properties and core toughness of 1.6582 better of 4140??? Thanks
