When the surface of the stainless steel shrapnel appear brown rusty spot, a lot of people will be surprised feel: stainless steel is not rusty, rust is not stainless steel, the problems may be steel. In fact stainless steel under certain conditions will rust. Stainless steel shrapnel relies on material surface to form a layer of a very thin and fine and stable solid rich chromium oxide film ( Protective film) To prevent the oxidation of oxygen infiltration, continue, and the performance of corrosion resistance. This protective film once attacked by a substance in the air or liquid oxygen atoms will constantly infiltration or metallic iron atom separation out unceasingly, forming loose iron oxide, metal surface are also constantly rust. This is damaged surface film, in the form of a lot of common with dust, metal particles, adhesion of organic liquid, etc. Precision contact: wish you a prosperous business, everything goes well, if you want to learn more dynamic, can scan the qr code, pay attention to the public. , is committed to precision stamping processing factory of the world's most professional electronic components
