ABSTRACT:
A method for coloring a stainless steel using a potential-time curve which comprises seeking for an individual coloring potential difference to be colored by compensating a standard coloring potential difference by difference between a standard inflexion point potential and an individual inflexion point potential, and stopping the coloring when the individual coloring potential changes in an amount corresponding to the individual coloring potential difference from the individual inflexion point potential.
