Corrosion is the result of the interaction of a material (metal)with its environment.Thee corrosion process depends on the properties of bothmetal (and alloy) and surrounding environment. Usually,the more important factors causing corrosion are concentrationof aggressive species (e.g., chloride), acidity (pH),fluid velocity, temperature, and potential (oxidizing power).Steel and other ferrous alloys are consumed in exceedinglylarge quantities because they have such a widerange of mechanical properties, may be fabricated withrelative ease, and are economical to produce. However, steelshave some distinct limitations, chiefly a relatively highdensity, a comparatively low electrical conductivity, andan inherent susceptibility to corrosion in some commonenvironments.
