Stainless steel with the development of the economy become more widely used, people in daily life is closely related to stainless steel, but many people understanding of the performance of the stainless steel is not much, know about the maintenance of stainless steel is much less. Many people think that stainless steel is not rusty, in fact, good corrosion resistance of stainless steel. Reason is forming a passivation layer on the surface of membrane, in the nature of it in a more stable oxide in in the form of that is to say, although stainless steel according to the different using conditions, oxidation degree is different, but in the end are oxidation, this phenomenon is commonly known as erosion.

All bare metal surface in corrosive environment, electrochemical reaction and chemical reaction, even from corrosion. Stainless steel surface passivation membrane ? weak corrosion resistance ability
