ISONITE® Li2Fe3 Nitriding

ISONITE® Li2Fe3 is a proprietary, high performance Ferritic Nitrocarburizing (FNC) process. FNC, more commonly known as salt bath nitriding, is a thermochemical diffusion process whereby nitrogen-bearing salts generate a controlled release of nitrogen at the interface of a ferrous part.  ISONITE® Li2Fe3 is a superior salt bath process that offers benefits above and beyond traditional salt bath processes including major environmental advantages.  Currently ISONITE® Li2Fe3 is only offered commercially by Parker Trutec MMi located in Sevierville, TN.
