304 stainless steel seamless pipe refers to the corrosion resistance of steel to corrosive media such as air, steam, water and weak acid, alkali, salt and other chemical corrosive media. Also known as acid-resistant stainless steel. The corrosion resistance of 304 stainless steel seamless pipe depends on the alloy elements contained in the steel. Chromium is the corrosion resistance of stainless steel to obtain basic elements. When the content of chromium in steel reaches about 12% chromium and oxygen corrosion medium, a thin oxide film (from passivation film) is formed on the surface of steel, which can further prevent the corrosion of steel substrates. In addition to chromium, 304 stainless steel seamless tube commonly used alloy elements nickel, molybdenum, titanium, niobium, copper, nitrogen, etc. to meet the requirements of stainless steel structure and performance of various uses. 304 stainless steel seamless pipe is a hollow round bar steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial pipelines and mechanical components. In addition, bending and torsion strength are the same and lighter, so it is widely used in manufacturing mechanical parts and engineering structures. It is also used in the production of various conventional weapons, barrels, shells and so on.
Firstly, the thicker the wall thickness of 304 stainless steel seamless pipe is, the more economical and practical it is, the thinner the wall thickness is, the higher the processing cost will be.
Second, 304 stainless steel seamless tube technology can determine its limitations, generally low seamless accuracy: uneven wall thickness of the inner tube, low brightness of the outer layer, high fixed length cost, and a little corrosion inside the outside, black spots difficult to remove;
Third, 304 stainless steel seamless pipe testing and forming must be off-line processing. Therefore, it embodies its superiority in high-pressure, high-strength mechanical structure.
