Why does stainless steel storage tank appear corrosion
Crevice corrosion
Crevice corrosion or oxygen accumulation battery corrosion occurs when certain deposits or attachments are present on the metal surface.
Second, corrosion
A stone may block the pipe of a copper alloy condenser. At this point, the downward direction of the rock will immediately produce turbulence. This causes erosion or wear of the copper protective oxide film and exposes the unprotected copper alloy metal, leading to further corrosion.
Third, pitting
Usually caused by a defect in a metal surface. The reaction is repeated and the metal perforation occurs rapidly.
Electrochemical corrosion
Electrochemical corrosion occurs when two or more different metals contact and connect in the presence of a conductive electrolyte.
In addition to the above points, the causes of partial corrosion of stainless steel storage tanks are peeling corrosion, selective leaching or alloy composition corrosion, intergranular corrosion, stress corrosion cracks and stress corrosion cracks, etc., which should be paid attention to in the practical application process.
