304 stainless steel seamless pipe is resistant to air, steam, water and other corrosive media and weak acid, alkali, salt and other corrosive media corrosion of steel. Also known as acid-resistant stainless steel. 304 stainless steel seamless pipe corrosion resistance depends on the alloy elements contained in steel. Chromium is the basic element of stainless steel corrosion resistance, when the steel containing chromium content of about 12%, chromium and oxygen in the corrosive medium, the steel surface to form a thin oxide film (from the passive film), to prevent Steel substrate further corrosion. In addition to chromium, 304 stainless steel seamless alloy commonly used alloying elements nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the various uses of stainless steel and organizational performance requirements. 304 stainless steel seamless pipe is a hollow bar, widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipes and mechanical structures. In addition, due to bending, the same torsional strength, light weight, so in the manufacture of mechanical parts and engineering structures has been widely used. Also used to produce all kinds of conventional weapons, guns, shells and so on.
First of all, 304 stainless steel seamless pipe thicker, more economical and practical, the thinner the wall thickness, processing costs will be substantially increased;
Second, 304 stainless steel seamless pipe technology to determine its limitations, the general seamless low accuracy: the uneven thickness of the inner wall, low brightness inside the tube, the fixed length of the high cost, and the hole outside, black spots difficult to remove;
Third, 304 stainless steel seamless pipe testing and plastic processing must be offline. Therefore, it shows its superiority in high-pressure, high-strength mechanical structure.
