Dear all
we manufacture rock shaft for tractors. material EN 19 with hardened n tempered with hardness 30 -35 HRC.after finishing we have to do induction hardening the splines and required case hardness 45-50 HRC case depth 2-3 mm..After induction hardening we are getting 55 to 57 hrc quench hardness.Recently we found cracking occurred in some shafts immediate after induction hardening.does adding polymer 5% will solve this problem?
regards
