For stainless steel valves, it is generally believed that they are not easy to rust, but in fact, stainless steel will rust. Stainless steel can be corrosion resistant because of the formation of a chromium-rich oxide film or passivation film on its surface. Tests have shown that when the chromium content reaches a certain proportion, the corrosion resistance of steel will change drastically, from being easy to rust to not being easy to rust, and from non corrosion to corrosion. In order to check whether the stainless steel valve will rust, the same valve can be placed in different environments for comparative analysis and verification. Generally speaking, if the stainless steel valve is placed in a relatively dry environment, the valve will not only be intact, but also will not rust for a long time.
If the stainless steel valve is placed in seawater with much salt, it will rust in a few days. Therefore, the corrosion resistance and other properties of stainless steel valves also need to be measured according to the social environment. From the characteristics of the stainless steel valve itself, the reason for the stainless steel is that there is a layer of chromium-rich oxide film on the surface to prevent external oxygen atoms and other particles from invading and damaging the object, so that the valve has the characteristics of being corrosion resistant. However, when the film is damaged by factors such as the environment, with the entry of oxygen atoms and the dissociation of iron ions, the stainless steel valve will rust. Experts say that there are many reasons for rust of the stainless steel valve, for example, the electrochemical reaction between the film and other metal element particles or dust. A micro-battery cycle as the medium is formed by moist air, which makes the stainless steel surface rust. Another important example is that the film on the stainless steel surface directly contacts with corrosive ionic liquids such as strong acid and alkali, causing social corrosion. Therefore, if you want the stainless steel valve not to rust, pay attention to cleaning items in daily use to keep the surface of the valve clean.
So, if stainless steel valves rust, how can users solve it? It is recommended that the surface of the stainless steel valve should be scrubbed and cleaned frequently to remove any external corrosion factors. Stainless steel 316 should be used in coastal urban areas, because stainless steel 316 can resist the corrosion of seawater.
The chemical composition of some stainless steel pipes on the market does not meet the corresponding national standards and cannot meet the requirements of stainless steel 304. Corrosion can also occur. In this regard, technicians said that users must carefully choose stainless steel valves made by reputable manufacturers when choosing them. Our stainless steel valves are your best choice, because they have good quality. Generally speaking, the safety valve made of stainless steel is very common to be seen, which is unmatched by other materials. Therefore, valves made of this material are very common to be seen in some hazardous media, which is also the key to ensuring their performance.
In addition, stainless steel valves are often exposed to some liquids, and the environment is usually wet. Our stainless steel valves have a major advantage, greatly extending the service life of the valve and eliminating the undue effect of possible rust.
