3. Faraday's Laws and Rate of Corrosion  
3.3 Example: Calculation of Corrosion in mdd 

Determine the corrosion rate of AISI 316 steel corresponding to 1 μA/cm^{2} of current. Following is the composition of the alloy (Note: Alternatively, you may get the composition of the alloy from ASM Handbook)
Cr = 18% Ni = 10% Mo = 3% Mn = 2% Fe = balance 
Solution: 
Using Equation 1 mA/cm^{2} = 0.128 (55.8 x 1)/(2 x 7.86) mpy shown in the previous section, we have
