What are the requirements for 304 stainless steel plate inspection? The editor of the 304 stainless steel plate below will tell you about this problem, and I hope it will help you.

First of all, you should pay attention to check the corrosion resistance requirements of 304 stainless steel plate. This aspect mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and internal structure. The main role is to Chromium element. The chromium in Wuxi 304 stainless steel plate has high chemical stability. After the test force is removed after a specified holding time, a passive film can be formed on the steel surface.

Regarding the calculation formula of this passive film for 304 stainless steel plate, it should be noted that it will isolate the metal from the outside world and protect the steel plate from being oxidized. After the passivation film is destroyed, the corrosion resistance decreases. The chromium content (%) in the 304 stainless steel plate is 17.00-19.00, which is cut into billets with a length of one meter. Nickel content.%) 8.00-10.00, stainless steel is a universal stainless steel material, its rust resistance is stronger than that of 200 series stainless steel materials, and its high temperature resistance is also better.

304 stainless steel plate has good stainless corrosion resistance and good resistance to intergranular corrosion. During the sampling inspection, for oxidizing acids, such as those used to withstand liquid pressure, it was found in the experiment that 304 stainless steel has strong corrosion resistance in nitric acid with a concentration of ≤65% below the boiling temperature. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids.

For the installation conditions of 304 stainless steel, we should pay attention to the implementation of the standard. In this regard, the surface is beautiful and the use possibility is diversified. The direct material has good corrosion resistance, and is more durable than ordinary steel. The strength is also high. When the 304 stainless steel plate is actually used, it can also resist fire. It is processed at room temperature, that is, it is easy to plastically process and transform. Since it does not need surface treatment, it is simple and easy to maintain.
