Don,

The exact alloy number may be cast into the crank somewhere so if you =
have the crank out of the engine, look for a number that starts with =
=E2=80=9CEN=E2=80=9D.  Problem is, you will have to look up what that is =
compared to US nomenclature.  Also, contrary to what I had always =
assumed, the TR motor=E2=80=99s crank is steel, not iron, and perhaps =
the Spit crank is as well.

0.010-0.020 is really deep for nitiriding and would actually be detrimental.=
  That sounds like a carburizing case depth spec.

0.003-0.006 is more typical for nitriding.
