Mils Per Year

Mils Per Year or MPY, is a measurement of corrosion and erosion.

MPY reports the loss of thickness of a material in Mils (thousandth of an inch) over a period of a year.

Although this gives engineers and technicians an overview on the corrosion of item, by its nature, MPY doesn’t give a measurement of specific local areas of corrosion of that item.
