Properties and uses of 316 and 316L stainless steel

更新日期:2013-06-05  浏览:1573

316 and 317 stainless steels are stainless steels containing molybdenum.  oil and gas pipeline The content of molybdenum in 317 stainless steel is a litter more than that in 316 stainless steel. Because the steel containing molybdenum, the overall performance of this steel is better than that of 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 is widely used. 316 stainless steel also has a good performance of chloride erosion, so it is usually used in the marine environment.316L stainless steel’s maximum carbon content is 0.03,  which can be used cannot be annealed after welding and the need for maximum corrosion resistance usesCorrosion resistanceThe corrosion resistance superior to that of 304 stainless steel, with good resistance to corrosion in the pulp and paper production process.316 stainless steel is resistant to erosion and erosion of marine and industrial atmospheres.Heat resistanceAt 1600 degrees below the continuous use and in continuous use under 1700 degree, 316 stainless steel has good resistance to oxidation. In the range 800-1575 degrees, continuous action is best not to 316 stainless steel, but the continuous use of 316 stainless steel in the temperature outside the scope, the stainless steel has good heat resistance.FinMin probing pipe imports Resistance of carbide precipitation of 316L stainless steel is better than 316 stainless steel, which can be used in the temperature range.Heat treatmentAnnealing at the temperature range of 1850-2050 degree, then quickly annealing, and then rapidly cooling. 316 stainless steel cannot bear heat treatment hardening.Welding316 stainless steel is of good welding performance. It can use all the standard welding method for welding. Welding can use, respectively by 316Cb, 316L or 309Cb stainless steel filler rod or electrode welding. To get the best corrosion resistance, welding 316 stainless steel section needs annealing treatment after welding. thermal expansion pipe If you use the 316L stainless steel, do not need annealing treatment after welding.Typical useUsed for outside building materials of pulp and paper equipment, heat exchanger, dyeing equipment, film processing equipment, pipeline and coastal areas.
