difference

At present, the two most commonly used stainless steels 304316 (or 1.4308,1.4408 corresponding to German / European standards), the main difference between 316 and 304 in chemical composition is that 316 contains Mo, and it is generally recognized that 316 has better corrosion resistance than 304 in high temperature environment. Therefore, in high temperature environment, engineers generally choose 316 parts. But the so-called thing is not absolute. In the concentrated sulfuric acid environment, never use 316 at any high temperature! Or it’ll be big. In order to prevent Mo from biting the thread, it is necessary to use a solid sulfur resistant crucible (Mo 2) to prevent it from biting the thread. Do you know that it is necessary to use a sulfur resistant material to prevent Mo 2 from biting the thread? Molybdenum crucible!)[ 2] : molybdenum can easily react with high valence sulfur ions to form sulfide. Therefore, no stainless steel is super invincible and corrosion resistant. In the final analysis, stainless steel is a steel with more impurities (but these impurities are more corrosion-resistant than steel). If it is steel, it can react with other substances.
