The corrosion resistance and other useful properties of the steel are enhanced by increased chromium content and the addition of other elements such as molybdenum, nickel, and nitrogen. There are more than 60 grades of stainless steel. he results collected from this study are validated with the morphological analysis of erosive surfaces which is attributed to the real wear mechanism. To characterize the eroded surfaces, this mechanism is associated with the micro-cutting, micro-plowing, plastic deformation and several other materials removal processes. Stainless steel is stable steel against rusting (corrosion) in atmospheric conditions and some harmful environments; type of alloy steel. The main alloying element that improves the corrosion resistance of steel is chromium (12-20%) (see Corrosion of Metals).
