Stainless steel sheets usually have good corrosion resistance, but they may still corrode in certain environments. The following are some common environmental factors that can cause stainless steel sheets to corrode:
Chloride environment: High concentrations of chloride ions (such as seawater, salt water, ammonium chloride, etc.) will corrode stainless steel and form pitting, intergranular corrosion, etc.
Strong acid and strong alkali environment: High concentrations of strong acids (such as sulfuric acid, hydrochloric acid) and strong alkalis (such as sodium hydroxide) will corrode stainless steel.
High temperature environment: Under high temperature conditions, the corrosion resistance of stainless steel may decrease, especially in high temperature environments with moisture or corrosive substances.
Chlorine-containing environment: Chlorine-containing gases (such as chlorine, hydrogen chloride, etc.) may also corrode stainless steel.
Oxygen-deficient environment: In an oxygen-deficient environment, such as a confined space or underwater environment, stainless steel will lose its passive protective film and easily corrode.
Metal dust and pollutants: Metal dust (such as iron powder, steel wire, etc.) and other pollutants may form local corrosion on the surface of stainless steel.
In order to improve the corrosion resistance of stainless steel sheets, you can choose suitable stainless steel materials and surface treatment, avoid exposure to corrosive environments, and perform regular cleaning and maintenance. The specific selection of suitable stainless steel materials and corresponding protective measures should be based on the actual use environment.
