All corrosion rates are in millimeters per year (mm/y); to convert to mils (thousandths of an inch) per year, divide by 0.0254.
Data are from Corrosion Laboratory Jobs 37-92, 29-94, 47-94, 42-95, and 14-96.
All tests were performed in reagent grade acids under laboratory conditions; field tests are encouraged prior to industrial use.
