snipped ......... Since the crank uses the same part number, regardless if it is hardened or
not, is there a visual inspection I can do to determine a Nitrided from a
non-Nitrided crank? ..........

------------------------------------------
Cleaned (not bead blasted) Tufftrided cranks are kind of a dark gray over all non-machined surfaces. File test a corner or as-forged surface. Even a new, sharp, name-brand file (use a non-working area down by the handle) will just skate across any Tufftrided surface without digging in at all.
