ASTM A554 Stainless Steel Pipe Tube AISI 304 22mm 316 Stainless Steel Tube

Stainless steel seamless pipe is a hollow long round steel, widely used in petroleum, chemical, medical, food, light industry, machinery and instrumentation and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also often used to produce various conventional weapons, barrels, shells, etc.

The two most commonly used stainless steels 304 and 316 (or 1.4308, 1.4408 corresponding to German/European standards). The main difference in chemical composition between 316 and 304 is that 316 contains Mo, and it is generally recognized that 316 has better corrosion resistance. , It is more corrosion resistant than 304 in high temperature environment. Therefore, in high temperature environments, engineers generally choose 316 material components. But the so-called nothing is absolute, in a concentrated sulfuric acid environment, no matter how high the temperature is, don't use 316! Otherwise, this matter may be a big deal. Anyone who learns machinery has learned threads. Remember that in order to prevent the threads from being seized at high temperatures, you need to apply a dark solid lubricant: molybdenum disulfide (MoS2). From it, you can get 2 points. The conclusion is not: [1] Mo is indeed a high-temperature resistant substance (do you know what crucible is used to melt gold? Molybdenum crucible!). [2]: Molybdenum easily reacts with high-valent sulfide ions to form sulfides. Therefore, no stainless steel is super invincible and corrosion-resistant. After all, stainless steel is a piece of impurity (but these impurities are more resistant to corrosion than steel^^). It is steel that can react with other substances.
