Fountain pumps are all basic metal materials, then when the acid salt when the salt is caused by what causes it?
Corrosion resistance of the product size is based on the metal material itself, the chemical properties and composition and use of the decision, such as 304 steel pipe, in the dry cleaning of the atmosphere, there are certainly good anti-corrosion ability, but it moved to the seaside area , In the sea fog rich in salt, will soon rust; and 316 steel pipe is doing well. Therefore, not any kind of stainless steel, in any environment can be resistant to corrosion, no rust.
All metal and oxygen in the atmosphere to react, in the form of an oxide film. Surprisingly, in the general composition of carbon steel on the continuous oxidation of iron oxide, so that corrosion continues to expand, and ultimately constitute holes. It is possible to use electroplating with paint or an oxidation resistant metal to assure the appearance of the carbon steel, but, as is known, such maintenance is only a thin film. If the maintenance layer is damaged, the following steel will begin to rust.
When the addition amount of chromium reaches 10.5%, the atmospheric corrosion resistance of the steel is remarkably added, but when the chromium content is higher, the corrosion resistance is not improved although the corrosion resistance is improved. The reason is the use of chromium alloying treatment of steel, the appearance of the oxide type changed to a similar composition of pure chromium metal surface oxides. This tightly adhered chromium-rich oxide maintains the appearance and avoids further oxidation. This oxide layer is extremely thin, through which it can see the natural appearance of the steel luster, so that the fountain pump with the appearance. Moreover, if the damage to the surface, the exposed surface of steel and atmospheric response to self-repair, from scratch to form this oxide "passivation film", continuing from the maintenance effect. Thus, all the stainless steel elements have a common characteristic, that is, chromium content of 10.5% or more.
