how to decide the time for case hardening?
how to decide the time for case hardening?
(OP)
i heard the rule of thumb in heat treatment is that one hour per inch. I assume this is meant to be through hardening. is there any rule of thumb for case hardening?





RE: how to decide the time for case hardening?
For a specific carburizing temperature:
Case Depth = k (square root of time)
Where k is a constant.
t is time (hours) at temperature.
Case Depth is in inches.
Hope this helps.
