Introduction
Stainless steel pipe is a kind of hollow long cylindrical steel. Its scope of application is used as pipeline for conveying fluid. It is mainly used in industrial transmission pipelines such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instruments and mechanical structural components. Stainless steel pipes are made of steel billets of acid and heat resistant grades, which are heated, perforated, sized, hot rolled and cut.
316 stainless steel properties
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 and is more corrosion resistant 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 environment of concentrated sulfuric acid, never use 316 at any high temperature! Or it'll be a big deal. People who study mechanics have all studied threads. I still remember a dark solid lubricant that needs to be applied to prevent threads from biting under high temperature: molybdenum disulfide (MoS2). From it, we draw two conclusions: No: [1] Mo is indeed a high-temperature resistant material (do you know what crucible Yellow Gold uses? 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 piece of steel with more impurities (but these impurities are more corrosion-resistant than steel). If it is steel, it can react with other substances.
