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 23-07 and 5-08.
All tests were performed in reagent grade acids under laboratory conditions; field tests are encouraged prior to industrial use.
