heat treatment method?
heat treatment method?
(OP)
Can somebody familiar with Italian Drawings tell me what 'cmt+tmp' mean?
I am fairly sure it is a note on heat treatment because it is followed by a HRc and case depth spec.
Thanks in advance.

RE: heat treatment method?
"Cementazione" or "cementato"
which means carburized or case hardened
tmp stands probably for
"Temperato" which means tempered
Between those should be also quenching but this is probably self evident.
