Carburizing only on 9310, 8620, etc.
Carbonitriding only on 1010, 1018, etc.

The biggest difference between the two processes is the ammonia issue.

What is the general reason for not carburizing 1010-1018-etc.?

Then again what about 1095?

Without the ammonia, the case won't harden if you just carburize 1010.  If you test the part surface after quenching, it will be soft.

1045 and above to 1095 usually have enough carbon in them to thru harden (depending on cross-section.  Neither are case hardened. (1045 has .45 Carbon and 1095 has .95 carbon).  A carburized surface usually has around 1.0 Carbon.
