Can one nitride mild steel? Nitride is a thin layer and it almost

precludes

regrinding. If a groove is more than .003 deep a nitrided end housings
is scrap. Also it can't be redone with embedded steel in an alloy casting
because of the high temp required.

I like the idea of through hardening as regardless of the
depth of the wear the wear surface can be reground. Lycoming claims

through

hardened steel cylinders. .035 4130 steel sheet is cheap here in the US.
