Can someone here tell me the method used to heat treat these to metals.
I am makeing a sin vice that is 9" long 4" wide and has a jaw depth of
1.750 out of 4130. I am also makeing some bending dies from 4140 and I
have the oven and I have quenching oil that I used to harden O1 drill
rod but I have ben given different conflicting versions on how to heat
treat these to types of metal.
some say 4130 water harden
some say 4140 oil harden
and some say oil for both or water for both?
Does someone here have the correct temp and what to quench these to
metals in. I am looking to get 52RC on these parts.
Regards
Stan
