Will stainless steel balls not rust directly from stainless steel
Is it true that stainless steel spheres do not rust? All materials of stainless steel will corrode, but the corrosion resistance of stainless steel of different materials is different, and the strength of Shaanxi extruder bearings varies. Stainless steel has the ability to resist air oxidation - that is, stainless steel properties, and also has the ability to resist corrosion in media containing alkali, alkali, and salt - that is, corrosion resistance.
However, the level of its corrosion resistance varies with the organic chemical composition, interactions, application standards, and types of natural environmental media of the steel itself. Stainless steel is a relatively stable chromium rich air oxide film (protective film) produced on its surface, which is ultra-thin, stable, and delicate, to prevent oxygen molecules from penetrating and oxidizing again, and to achieve corrosion resistance.
Once there are various reasons, such plastic films are constantly damaged, and oxygen atoms in the gas or liquid will continue to penetrate or iron atoms in the alloy will continuously separate, producing loose compounds, and the metal surface will also suffer from continuous rusting.
The ball of a ball valve fluctuates, and under the working pressure of the medium, the stainless steel ball can cause a certain deviation and press tightly against the protruding surface at the outlet end, ensuring the sealing of the outlet end. The structure of the Shaanxi extruder bearing fluctuation ball valve is simple and has good sealing performance. However, the ball bears all the load of the medium during operation and is sent to the outlet sealing ring. Therefore, it is necessary to consider whether the sealing ring material can withstand the working load of the ball medium. When subjected to high working pressure, the ball is likely to deviate.
This type of construction is generally suitable for low to medium voltage ball valves. The main characteristics of the ball valve are the compact structure, reliable sealing, simple construction, and convenient maintenance of the bearing body of the Shaanxi extruder. The protruding surface and curved surface of the bearing of the Shaanxi extruder are often in a closed state. The bearing of the Shaanxi extruder is not easily eroded by the medium, making it easy to use and maintain. It is suitable for general working media such as strong electrolytes, organic solvents, acids, and gases, and is also suitable for harsh working media such as O2, hydrogen peroxide, methane gas, and ethylene. It has been widely used in various fields for the bearing of Shaanxi extruders. The bearing oil circuit plate of the ball valve Shaanxi extruder can be integral or assembled.
