HEAT TREATMENT PROCESS FOR CARBORIZED EN353 FOR YOKES
HEAT TREATMENT PROCESS FOR CARBORIZED EN353 FOR YOKES
(OP)
WE ARE MANUFACTURING AUTOMOTIVE YOKES FROM MATERIAL EN353. BECAUSE OF LOW CARBON IN THIS MATERIAL WE ARE CARBORIZING AND THEN INDUCTION HARDINING IT. THE PROBLEM WE ARE FACING IS THAT AFTER IT IS HARDNED AND CARBORIZED WE ARE UNABLE TO MACHINE THE CRITICAL FITMANT PARTS WHERE THE CROSS FITS.IF WE MACHINE IT BEFORE CARBORIZING IT THEN THE TOLLERANCESES GETS AFFECTED. IS THERE ANY ALTERNATE WAY TO HEAT TREAT EN353 FOR THE ABOVE MENTIONED PROBLEM? PLEASE HELP
RE: HEAT TREATMENT PROCESS FOR CARBORIZED EN353 FOR YOKES
Alternativly harden and temper the part then gas or salt bath nitride the selected areas requiring wear resistance. EN353 is suitable for nitriding and will produce an adherent wear resistant case. Remember to temper after hardening at a temperature in excess of your nitriding temperature provided your core hardness specification will allow such treatment. The nitriding operation if conducted at a temperature below the tempering temperature will stop part distortion and the only grinding allowance will be that necessary to compensate for the build up in the nitrided coating.
