Determine the corrosion rate ( mpy ) of steel corresponding to 1µA / cm? of current. Following is the composition of alloys. Cr = 21%, density = 7.1 g/ cm', At.wt. = 52.01 g /mol, number of electron = 1 Ni = 8%, density = 8.9 g/ cm', At.wt. = 58.68 g /mol, number of electron = 2 Fe = 70%, density = 7.86 g/ cm', At.wt. = 55.85 g /mol, number of electron = 2 Note : Faradays constant = 96500 coulombs per mole of electrons. C= constant which includes F and any other conversion factor for unites, for instance, C = 0.129 when corrosion rate is in mpy.
