I manufacture thin walled, bearing outer like components from bearing steel (SAE 52100). After machining it undergoes heat treatment where it attains 62-63 HRc of hardness.
Currently I use Mar Quenching method (outsourced) to prevent temperature shock of quenching in Oil. Recently I came to know that few of my competitors heat treat by Sealed Quenching method.
Post heat treatment, they are polished in vibratory and centrifugal polishing machines and later hard chrome plated.
I discussed with my service provider and he is unable to point to any major benefit of using Sealed Quenching over Mar Quenching.
Can the experts here please guide me in the matter.
