Definitions for "Corrosion rate"
Keywords:  corrodes, mpy, mdd, sematech, decimeter
The speed (usually an average) with which corrosion progresses (it may be linear for a while); often expressed as though it were linear, in units of mdd (milligrams per square decimeter per day) for weight change, or mpy (milligrams per year) for thickness changes.
expressed in inches or millimeters of steel (or other defined material) per year, at a stated temperature.
the amount of material removed by a corrosive chemical in unit time at a given temperature, normally expressed in inches per year. [SEMATECH
The speed at which corrosion occurs on a particular substance.
