Stainless steel valve stainless steel is resistant to weak corrosive medium such as air, steam, water and acid, alkali, salt and other chemical etching medium corrosion of the steel. Also called acid-proof stainless steel. Practice, we often call the weak corrosive medium corrosion resistant steel, stainless steel and medium resistance to chemical corrosion of steel called acid-resistant steel. Due to the chemical composition on the difference between the two, the former does not necessarily medium resistance to chemical corrosion, while the latter are generally not rust. The 'stainless' in the stainless steel valves, stainless steel, not stainless steel valves will not rust, but relatively under certain conditions is not rust. If the user use undeserved, its use in environment or conditions beyond the corrosion resistant ability, nature also will rust. Stainless steel valves used stainless steel corrosion rusty condition, it may also be because manufacturer selection is not reasonable, the manufacturers for the product use and choose the wrong stainless steel grades do raw material, may also be a manufacturer of production and processing technology does not pass. In addition, the manufacturer really choose the authority on the market do not conform to the relevant country or industry standard and inferior stainless steel raw materials. Use stainless steel valves stainless steel liquid, to a certain extent, you can easily see the market some of the fraud and counterfeit stainless steel face. Buy 304 grades of stainless steel, for example, '304' on vendor products for testing. If really 304, liquid is measured by the '304' or 'Ni8' type hydraulic test, corresponding testing results should appear, otherwise, is not really material 304. If the liquid was determined by 'low Ni' further tests found medicine beads are purple, suggests that the product is a kind of high manganese steel, and is likely to be current popular on the market and inferior stainless steel corrosion resistance is very low, that is, the '200 series stainless steel'. Stainless steel Industrial Valves, stainless steel not to rust and corrosion resistance is due to its rich chromium oxide film on the surface ( Passivation film) The formation of. This is not to rust and corrosion resistance is relative. Experiment shows that the steel in the atmosphere, the weak medium such as water and nitric acid oxidation, such as medium, its corrosion resistance increase with the increase of chromium content in steel, when the chromium content reaches a certain percentage of steel corrosion resistance mutation, that is, from easy to rust is not easy to rust, never corrosion resistant to corrosion. Engaged in stainless steel industry knows that unless it is to play the head donkey, otherwise no one will give you assurance does not rust. It is thought that stainless steel is never rust, actually this is the lack of the understanding of stainless steel is a unilateral mistake. Stainless steel is not must not rust, just in the same environment than other steel corrosion rate is much lower, sometimes even can be neglected. But not any kind of stainless steel, in any environment can not rust. Stainless steel is formed on the surface of 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 ability to resist corrosion. Once you have some reason, the film has been continuously destroyed and air or oxygen atoms in the liquid iron atoms will constantly infiltration or metal separation out unceasingly, forming loose iron oxide, metal surface are also constantly rust.
