[TheForge] Heat Treating Hitch Pins

Fri Sep 19 02:47:00 2003

Ed:  I would use extreme caution in heat treating shock-susceptible pins.
If you make them brittle, they will break vs. bend.  A bent pin may hold,
but a broken pin might not.  If you fully harden this pin, I would recommend
tempering it back to a full blue color.  I would recommend tough over hard
in this application...oil vs. water quench and temper to blue from
brightened steel.

enuf quench in water.
