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

Higher strength helps, but only if the other two factors area also in your favor.

The 4340 can be excellent shaft material, if you require it, because of the deep hardenability it possesses. You can find fatigue properties for comparison and the 4340 will typically win out.
