We are attempting to induction harden shafts in a vertical scanning operation, and we are getting so much distortion that the shafts cannot be straightened, (without breaking) after hardening. The shafts are 1.875” diameter, 1547 continues cast material, (Mac Steel, formerly North Star, Monroe)...
Can anyone tell me what the recommended atmosphere exchanges per hour should be during a carburizing cycle. We are using endothermic and enriching with methane. Thanks in advance.
We operate a captive induction hardening operation where we harden shafts for the automotive industry. We use Lakos separators to remove the scale from our systems, but have not found an effective means of removing tramp oils. Our parts come out stained and seem to rust quickly after tempering...
