316 and 316L stainless steel
316 and 317 stainless steel (see below the performance of 317 stainless steel) is a stainless steel containing molybdenum. 317 stainless steel molybdenum content slightly Gaoming in 316 stainless steel. Because of molybdenum in steel, the steel performance is better than 310 and 304 stainless steel, under the condition of high temperature, when the concentration of sulfuric acid is less than 15% and more than 85%, 316 stainless steel has a wide range of uses. 316 stainless steel also has good and chloride erosion performance, so is usually used for marine environment.
The maximum carbon content of 316L stainless steel 0.03 can be used for welding can not be annealed and the use of maximum corrosion resistance. Corrosion resistance of better than 304 stainless steel, in the pulp and paper production process has a good corrosion resistance. And 316 stainless steel is also resistant to the erosion of marine and corrosive industrial atmosphere.
Heat resistance
At 1600 degrees below the discontinuous use and continuous use of 1700 degrees below, 316 stainless steel has good oxidation resistance. In the range of 800-1575 degrees, it is best not to function continuously 316 stainless steel, but the temperature range outside the use of 316 stainless steel, the stainless steel with good heat resistance. The carbide precipitation of 316L stainless steel is better than that of 316 stainless steel, and can be used above temperature range.
Heat treatment
The temperature range of the 1850-2050 is annealed, then rapidly annealed, and then rapidly cooled. 316 stainless steel can not heat treatment hardening.
Welding
316 stainless steel has good welding performance. Can use all the standard welding method for welding. Welding can be used according to the use of 316Cb, 316L or 309Cb stainless steel filler rod or welding electrode. In order to obtain the best corrosion resistance, the welding cross section of the 316 stainless steel need to be annealed and annealed.. If you use 316L stainless steel, do not need to post annealing treatment.
Typical use
Heat exchangers, dyeing equipment, film flushing equipment, piping, coastal zone building materials for pulp and paper.Catalog printing
