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/cm2 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


Using Equation  1 mA/cm2 = 0.128 (55.8 x 1)/(2 x 7.86)  mpy shown in the previous section, we have
