Therefore, the use environment of stainless steel is required, and it needs to be wiped regularly to remove dust and keep it clean and dry. In the United States, there is an example: An enterprise uses an oak container to hold a solution containing chloride ions. The container has been used for nearly 100 years. It was planned to be replaced in the 1990s. Because the oak material is not modern enough, the container is replaced with stainless steel after 16 days. Leakage due to corrosion.
Second, no solution has been dissolved in the alloy elements did not dissolve into the matrix, resulting in low matrix alloy content, poor corrosion resistance.
Third, this material that does not contain titanium and niobium has the inherent tendency of intergranular corrosion. The addition of titanium and niobium, together with a stable treatment, can reduce the intergranular corrosion.
A high-alloy steel that resists corrosion in air or in chemically corrosive media. Stainless steel has an aesthetically pleasing surface and good corrosion resistance. It does not require surface treatment such as plating, and it exerts the inherent surface properties of stainless steel. A type of steel, usually called stainless steel. Representative performance of 13 chrome steel, 18-8 chromium nickel steel and other high alloy steel.
From the metallographic point of view, since the stainless steel contains chromium and forms a thin chromium film on the surface, this film separates and invades oxygen from the steel and acts as a corrosion resistance.
In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 12% chromium.
Normally closed air valve is a type of solenoid air valve that is designed to remain closed when there is no power or air pressure applied to it. It is commonly used in pneumatic systems to control the flow of air or other paths. The valve is closed by a spring and is opened by the application of air pressure or electrical power.
These solenoid valves use an electromagnetic coil to open and close the valve. They are commonly used in automated systems and can be controlled remotely. Usually the air valve is used to match with Mini Air Pump or Mini Vacuum Pump. They are widely used for massagers and healthcare devices.
