不锈钢种类（Type of stainless steel）.doc

不锈钢种类（Type of stainless steel） Generally, 201, 202, 304, 316, and more 316 and 317 stainless steel (after the performance of 317 stainless steel) are of molybdenum stainless steel. The molybdenum content of 317 stainless steel was a little bit clever than 316 stainless steel. Because of molybdenum in steel, stainless steel, the steel grade overall performance is better than 310 and 304, under the condition of high temperature when the concentration of sulfuric acid is less than 15% and higher than 85%, the 316 stainless steel has a wide range of USES. 316 stainless steel also has good performance of chloride erosion, so it is commonly used in Marine environment. 316 l stainless steel 0.03, the biggest carbon content can be used for welding cannot undertake after annealing and maximum use of corrosion resistance Corrosion resistance is better than that of 304 stainless steel, corrosion resistance in the process of pulp and paper production has good corrosion resistance performance. And 316 stainless steel is also resistant to the sea and erosion of the industrial atmosphere. Heat resistance is used intermittently under 1600 degrees and in continuous use under 1700 degrees. 316 stainless steel has good oxidation resistance. In the range of 800-1575, it is best not to continuously use 316 stainless steel, but the stainless steel has good heat resistance when using 316 stainless steel. The stainless steel of 316L stainless steel is better than 316 stainless steel and can be used in the above temperature range. Heat treatment annealed in the temperature range of 1850 to 2050, then quickly annealed and then cooled rapidly. Stainless steel can not overheat treatment for hardening. Welding 316 stainless steel has good welding property. All standard welding methods are available for welding. 316Cb, 316L or 309Cb stainless steel packing rod or welding rod are used for welding. In order to obtain the best corrosion resistance, the welding section of 316 stainless steel steel
