RE: Equivalent to a European Nitriding Grade

Hi,
there is not an exact american equivalent with the same chemical composition.
Depending on your needs you could select an american nitriding steel with a different composition.
If that suits you, the following are available:
AMS 6470 (aka 135 Mod.) UNS = K25065 or
AMS 6471.
Bye,
