Case
34CrNiMo6 to Ø580
The customer had a shaft with a hardness requirement at Ø580 and a diameter where 42CrMo4 would lose the core. We switched to 34CrNiMo6, had the bar +QT to the value and sawed to part lengths the turning shop could take directly.
The delivery
Round bar 1.6582, heat treated, sawn, 3.1 with mechanical values after treatment. Not a certificate that only showed the heat.
Why not 42CrMo4
In that diameter 1.7225 could not promise the core. The comparison between 42CrMo4 and 34CrNiMo6 explains the choice.
