420 stainless steel induction hardening
420 stainless steel induction hardening
(OP)
Is it possible to induction harden 420 stainless steel to 50-60 HRC at 1.5 to 2mm deep.
My supplier is advising that he has 420 but can only obtain 46-48 HRC

(ie quench at sub zero effects of this etc...)

2.There may be some retained austenite after quench which would require sub-zero treatment to transform and give you your final couple of points of hardness.
3. the carbon level of the alloy will have to be at the high end of the range to get the greatest possible hardness.
