Hardening technique questions
(OP)
was wondering if anyone knows why you would NOT carburize a part made of cast iron?
and what is the advantage of nitriding over carurizing?

RE: Hardening technique questions
To answer your second question, I found this interesting article by Milwaukee gear that compares carburizing with nitriding and carbonitriding.

We used to flame harden a Ductile Iron hub for wear resistance. Though you had to be very careful, it did work well, though I would not want to do it for a high volume part.
RE: Hardening technique questions
Agreed. My focus was on gray cast iron versus nodular iron, which has increased ductility and toughness.
RE: Hardening technique questions
There is an art to flame hardening cast iron and should only be undertaken by one versed in the art.
