surface hardness
(OP)
Dear all
We are facing a different problem in induction of rock shafts of tractor.we have inductotherm medium frequency induction hardening machine. we required 2.5 mm to 3 mm case depth at 45 hrc in there and surface hardness is 50 hrc after tempering.we are getting proper depth when u cut the section and check but surface hardness is varying alot when we check on splines.our polymer ratio is 5% to water..please advise.
regards.

Also, I agree with TVP that surface decarb might be an issue.
