3x3 316 Stainless Steel Sheet Plate 2b Sus409 Width 2000mm
1. Introduction
The use of 316 stainless steel plate with the development of the economy becomes more widely, people in daily life and stainless steel is closely related, but many people on the performance of stainless steel knowledge is not much, 316 stainless steel plate maintenance will know less. Many people think that stainless steel is never rusty, in fact, stainless steel corrosion resistance is good. The reason is the formation of a passivation film on the surface, which exists in nature as a more stable oxide form. That is to say, although stainless steel is used under different conditions, the degree of oxidation is not the same, but eventually are oxidized, this phenomenon is usually called corrosion. The metal surface exposed in the corrosion environment all occurs electrochemical reaction or chemical reaction, uniform corrosion.
In the PASSIvation film on the surface of 316 stainless steel plate with weak corrosion resistance, the pitting reaction is formed due to the self-excitation reaction and the formation of small holes, coupled with the proximity of chloride ions, the formation of a strong corrosive solution, and the speed of corrosion reaction is accelerated. There are intergranular corrosion cracking inside the stainless steel, all of these, on the surface of the stainless steel plate passivation film are destroyed. Therefore, the stainless steel surface must be regularly cleaned and maintained, in order to maintain its gorgeous surface and extend the service life.
