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...
In the stainless steel plate process, if the temperature of the steel is not uniform, the material flows more in the area with higher temperature, and less in the part with lower temperature, and the high temperature difference causes cracking. The wedge is a measure of the thickness at an edge compared to the average thickness of the edge of the strip or plate. It is desirable to have some bulge in the steel piece so that rolling can be performed with high stability. Roll springs are a defect in which the thickness of the rolled sheet is greater than required, the rolls have been deflected by the high rolling force, and elastic deformation of the mill occurs. Roll deformation can be reduced if a stiffer roll is used, ie a roll material of high stiffness or spring constant. Maintaining a uniform gap is difficult, the rollers deflect under the load required to deform the steel, the deflection results in the steel being thinner at the edges and thicker in the middle, which can be overcome by using crowned rollers, but crowned rollers compensate for a set of conditions, temperature and Deformation, other methods of compensating for roll deformation include...
Stainless steel products are widely used in our daily production and life. For example, our doors and windows, bridges, tools used, etc. are used, which provides us with a lot of convenience. So what problems should we pay attention to when welding stainless steel to ensure the quality of our products? When welding stainless steel products, it is necessary to pay attention to the need to work in a good working environment; in the process of welding stainless steel products, it is necessary to pay attention not to wear glue gloves for processing, because the temperature is too high during welding, and the glue Gloves are easily melted by high temperature; during the welding process, do not touch the relevant welding tools; when cutting stainless steel, it is strictly forbidden to directly cut the stainless steel material stack, and the stainless steel plate should be moved to the site for cutting; if using Manual arc welding requires an anti-spatter coating with a range of 100mm on both sides of the street to easily clean up spatter; during the processing, it is necessary to strictly control the number of cold wind repairs of the stainless steel pressure vessel. It is also...
