What are the models of stainless steel?
heat treatmentAnnealing is carried out in a temperature range of 1850-2050 degrees, followed by rapid annealing and then rapid cooling. 316 stainless steel shall not be overheated to harden.welding316 stainless steel has good weldability. All standard welding methods can be used for welding. Welding can be carried out according to the use of 316Cb, 316L or 309Cb stainless steel filler bar or welding rod for welding. In order to obtain the best corrosion resistance, the welded section of 316 stainless steel needs to be annealed after welding. If 316L stainless steel is used, there is no need for post weld annealing.
The maximum carbon content of 316L stainless steel is 0.03, which can be used in welding and can not be annealed and requires maximum corrosion resistanceCorrosion resistanceBetter corrosion resistance than 304 stainless steel, in the pulp and paper production process, has good corrosion resistance. Also, 316 stainless steel is also resistant to erosion by oceanic and corrosive industrial atmospheres.Heat resistance316 stainless steel has good oxidation resistance at discontinuous intervals below 1600 and for continuous use below 1700 degrees. In the range of 800-1575 degrees, it is better not to continue the role of 316 stainless steel, but in the temperature range other than the continuous use of 316 stainless steel, the stainless steel has good heat resistance. 316L stainless steel has better carbide precipitation resistance than 316 stainless steel, and can be used in the above range of temperature.
Generally 201202304316, these 202 and 304 use more316 and 317 stainless steel (see below the performance of 317 stainless steel) is a stainless steel containing molybdenum. The molybdenum content in 317 stainless steel with 316 stainless steel. Due to a little of molybdenum in steel, the steel overall performance is better than 310 and 304 stainless steel, high temperature, when the concentration of sulfuric acid is less than 15% and more than 85%, 316 stainless steel has been widely used. 316 stainless steel also has good chloride corrosion resistance, so it is often used in marine environments.
