4140 steel and color case hardening compatibility
20/09/13 08:16 PM

I've been looking at info about color case hardening(CCH) steel parts, but there seems to be loads of conflicting input at to CCH on a 4140 steel part. I was wondering if anyone has done(or had done) a CCH finish on a part made from 4140? In reading posts here and other places, that 4140 can be done but may require different variables in the process(I.e. temp of the furnace, time in furnace, quech water temp etc.). I know Doug turnbull CCH ruger no 1 receivers, which are made from 4140(may be wrong), is it any more difficult than regular low carbon steel? I have seen several parts of 8620 steel CCH, and that is a chrom-moly steel correct?
I've always love the look of a color case hardened receiver and would really love one for myself.
