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.   Li2Fe3 is a superior salt bath process that offers benefits above and beyond traditional salt bath processes including major environmental advantages.  Currently Li2Fe3 is only offered commercially by Parker Trutec MMi located in Sevierville, TN.
