Question:

How does stainless steel resist erosion-corrosion?

Answer:

Stainless steel resists erosion-corrosion due to its unique composition and protective oxide layer. The high levels of chromium in stainless steel form a thin, stable oxide layer on the surface, which acts as a barrier against corrosive agents. This oxide layer self-repairs if damaged, preventing further corrosion and erosion of the steel. Additionally, the presence of other elements like nickel and molybdenum enhances the steel's resistance to erosion-corrosion in harsh environments.
Stainless steel resists erosion-corrosion due to its unique composition and protective layer formed by chromium. The chromium in stainless steel reacts with oxygen in the atmosphere to create a thin, invisible oxide layer on the surface, known as the passive layer. This passive layer acts as a barrier, preventing direct contact between the metal and corrosive elements, such as water or chemicals. Additionally, stainless steel contains other alloying elements like nickel and molybdenum, which further enhance its resistance to erosion-corrosion.
Stainless steel resists erosion-corrosion due to its unique composition and protective oxide layer. The addition of chromium in stainless steel forms a passive oxide layer on its surface, which acts as a barrier against corrosive agents. This oxide layer regenerates when damaged, providing continuous protection against erosion and corrosion.
