The chemical composition of 316 stainless steel in addition of molybdenum, so its corrosion resistance, has greatly improved high temperature strength, high temperature resistant degree is as high as 1200-1300, can be used in relatively harsh environment.
In addition, the corrosion resistance of the 316 stainless steel is better than that of the 304 stainless steel. In the pulp and paper production process, if the equipment is made of 316 stainless steel, its corrosion resistance will be better. And 316 stainless steel is enough to withstand the erosion of marine and corrosive industrial environments.
316 stainless steel products can be used in the environment below 871 degrees C, and can be used for a long time in the environment of 927C degrees or more. And the oxidation resistance of 316 stainless steel products is also very good. But in the range of 427 degrees C-857 degrees C, it is best not to continue to use 316 stainless steel, but in the temperature range beyond the continued use of 316 stainless steel material, still can have very good heat resistance. At the same time, it is also noted that the precipitation resistance of 316L stainless steel is stronger than that of 316 stainless steel, and can also be used in the above temperature range. 316 stainless steel plate can not be hardened by heat treatment.
In addition, the weldability of the 316 stainless steel is also very good, can be used almost all the standard welding method for welding. When welding, 316Cb, 316L or 309Cb stainless steel filler rod or electrode can be used as solder. However, it is necessary to note that in order to obtain the best corrosion resistance, it is generally necessary to do the post weld annealing treatment of the welded section of 316 stainless steel. However, if the 316L stainless steel is used, there is no need to do the post weld annealing treatment.
316L stainless steel mentioned above, then the next introduction of 316L stainless steel bar. This steel can be used for the production of heat exchanger, dyeing equipment, film materials for external equipment, pipelines, coastal areas of the building or flushing, senior watch chain, case etc.. In addition, it can also be used to produce equipment, chemical dyes, paper making, oxalic acid, fertilizer and other equipment in sea water environment, as well as photography, food industry, coastal area facilities, ropes, CD rods, bolts, nuts.
The maximum carbon content of 316L stainless steel is 0.03, which can be used after welding and can not be annealed and need maximum corrosion resistance.
Because 316L is also a molybdenum stainless steel, its performance is better than that of 310 and 304 stainless steel. At high temperature, when the concentration of sulfuric acid is less than 15% or higher than 85%, the use of 316L stainless steel is more extensive. In addition, 316L stainless steel also has excellent resistance to chloride erosion, so the performance in the marine environment is also very strong.
316L stainless steel can be used in the middle 1600 degrees off the following environment, continuous use at 700 degrees below, 316L stainless steel has good oxidation resistance, in the range of 800-1575 degrees, then try to avoid continuous use. But the 316L stainless steel can be continuously used outside the temperature range, and the heat resistance is better. The precipitation resistance of 316L stainless steel is better than that of 316 stainless steel, which can be used in the above temperature range. In addition, the 316L stainless steel can be annealed in solid solution at 1010-1150 degrees of temperature and then cooled rapidly. What is needed to know is that the 316L stainless steel can not be hardened after heat treatment.
316L stainless steel has excellent welding properties and can be welded with all standard welding methods.
