316 stainless steel has improved its corrosion resistance and high temperature strength due to the addition of Mo element. Its high temperature resistance can reach 1200-1300 degrees, and it can be used under the condition of cauku. 3. Application: equipment used in seawater, chemical, dye, paper making, oxalic acid, fertilizer and other production equipment; photo, food industry, coastal facilities, rope, CD rod, bolt, nut. The density of 304 stainless steel 7.93 g / cm3 austenitic stainless steel generally uses this value 304 chromium content (%) 18-20.304, which is equivalent to 0Cr19Ni9 (0Cr18Ni9) stainless steel in China, 304 stainless steel is a universal stainless steel material, and its antirust performance is better than that of 200 series stainless steel. High temperature resistance is also good, as high as 1000-1200 degrees. 304 stainless steel has excellent corrosion resistance and good intergranular corrosion resistance. For oxidizing acid, it is found that 304 stainless steel has strong corrosion resistance in nitric acid with concentration less than or equal to 65% of boiling temperature. It also has good corrosion resistance to alkali solution and most organic and inorganic acids.

And the price of 316 stainless steel distribution box is very high. So it's OK to use 304 stainless steel distribution box. 316 this guy is too nice, too expensive, no need. 304 stainless steel can completely meet the standard. Of course, some willful enterprises will use 316, which is OK. Of course, some special environments can only use 316 stainless steel.
