  • DuraChrome Hard Chromium Plating

    Hard chrome deposits have a hardness range from 56 74 R.C. depending on the bath type used. Obviously, the higher the R.C. (Rockwell C) number the longer the service life will be provided to the component. Deposit hardness is a function of the bath chemistry used. Thus it is best to use a plating process that provides the highest R.C. value.
