304 seamless pipe, no blisters, no sand hole, no spots, no cracks, flat bead. Bending, cutting, welding performance advantages, nickel content is stable, the product conforms to China GB, the United States ASTM, Japan JIS and other specifications!
Product details editor
304 seamless pipe is resistant to air, steam, water and other weak corrosive medium and acid, alkali, salt and other chemical corrosive medium corrosion of steel pipe. Also called stainless acid resistant steel pipe.
304 the corrosion resistance of seamless tubes depends on the alloying elements contained in the steel. Chrome is made of stainless steel corrosion resistance for the basic elements, when the Cr content in steel reaches about 12%, the oxygen effect of chromium and corrosive medium, to form a thin film on the surface of steel (self passivation film), the matrix can prevent further corrosion of steel. In addition to chromium, stainless steel seamless tubes are commonly used alloying elements as well as nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various uses on the structure and properties of stainless steel.
304 seamless pipe is a hollow strip of round steel, widely used in petroleum, chemical, medical, food, light industry, machinery, instrumentation and other industrial pipelines and mechanical components. In addition, the bending and torsional strength of the same weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.
Feature editor
304 the thicker the wall of seamless tube is, the more economical and practical it is. The thinner the wall thickness is, the higher the processing cost will be;
304 process seamless pipe limits its performance, generally low precision seamless steel pipe: uneven thickness, the appearance of low brightness tube length high cost, and the internal and external surface pitting and black spots difficult to remove;
304 seamless inspection and plastic processing must be off-line. Therefore, it reflects its superiority in high pressure, high strength, mechanical structure and timber
