The difference between stainless steel 304 and 316

          Now the two most commonly used stainless steel 304,316 (or the corresponding Ude/European 1.4308), 316 and 304 in the chemical composition of the most important difference is 316 contain MO, and generally recognized that 316 corrosion resistance is better, than 304 in the high-temperature environment more corrosion resistance. Therefore, in the high-temperature environment, engineers will generally choose 316 of the material components. But the so-called thing is not absolute, in the thick sulfuric acid environment, again high temperature also do not use 316! Otherwise it would have been a big deal. The mechanics have learned the thread, remember to prevent the thread from biting dead at high temperatures, a dark solid lubricant that needs to be smeared: molybdenum disulfide (MoS2), from which it came to 2 conclusions not: [1 Mo is indeed a high-temperature-resistant substance (know what crucible is molten gold?) Molybdenum Crucible! )。 [2]: Molybdenum is very easy to react with high valence sulfur ions to generate sulfide. So no stainless steel is super resistant to corrosion. In the final analysis, stainless steel is a piece of impurities (but these impurities can be more corrosion-resistant than steel ^ ^) More steel, is steel can and other material reaction
