(7) TP 309/309S Stainless Steel Seamless Pipe Tube Corrosion Resistance
309S seamless Stainless steel pipe is stainless steel seamless steel tube series. According to the national standard GB/T 14976-2002 (fluid conveying stainless steel seamless steel tube), GB/T 14975-2002 stainless steel seamless tube (structure), GB/T 13296-91 (Boiler, stainless steel seamless steel tubes for heat exchanger). Finished products are pass strict inspection.
309S seamless stainless steel pipe no blister, no sand hole, no black spots, no cracks, because of the process of bending, cutting, and welding. Products is accordance with chinese GB, American ASTM, Japan JIS, etc. 309S seamless stainless steel pipe is weak corrosive medium such as air, steam, water resistance and acid, alkali, salt and other chemical etching medium corrosion of the steep pipe also called stainless acid-resistant steel pipe.
The corrosion resistance of 309S seamless stainless steel pipe depends on the alloy element content in the steel. Chromoum is the basic element to stainless steel for corrosion resistance. when about 12%chromium content is steel, chromium and the role of oxygen corrosion medium. In the steel surface to form a thin layerof oxide film (since the passivation film) can to prevent further corrosion of steel substrate. In addition to the chromium, stainless steel seamless tube commonly used alloying elements and nickel, molybdenum, titanium, niobium, copper, nitrogen, etc. In order to meet the requirements of various kinds of application on the microstructure and mechanical properties of stainless steel.
309S seamless stain less steel pipe is a hollow circular steel strip. It is widely used in petroleum, chemical, medical, food, light industry, machinery, instrument and other industrial pipeline and mechanical structure parts, etc. In addition, at the same time in the bending and torsional strength phase, lighter weight, it is widely used in the manufacture of machinery parts and engineering structures.. Also commonly used for the production of various kinds of conventional weapons, barrel, shells, etc.
309S seamless stainless steel pipe wall thickness is thicker, it is more economical and practical. The Thinner wall thickness, its processing costs wil rise significantly.
309S seamless stainless steel pipe process decide the limits of its performance. Generally low preicision seamless steel tube, wall thickness is not uniform, the tube surface brightness is low, length high cost and the appearance and pitting, black is not easy to remove. 309S seamless stainless steel pipe detection and plastic must be offline processing, so it is in high pressure and high strength material.
