(1) The anode polarization curve of the stainless steel has a stable passivation zone for the specific medium used.
(2) Improve the electrode potential of the stainless steel matrix and reduce the electromotive force of the corrosion galvanic cell.
(3) Make the steel with single-phase structure, reduce the number of microcells.
(4) The formation of stable protective film on the surface of steel, such as steel silicon, aluminum, chromium, etc., in many corrosion and oxidation occasions can form a dense protective film, improve the corrosion resistance of steel.
(5) To reduce or eliminate various non-uniform phenomena in steel is also an important measure to improve the corrosion resistance of steel.
Adding alloying elements into steel is the main method to improve corrosion resistance. Adding different alloying elements can produce effects through one or several ways at the same time to improve corrosion resistance of steel.
