201 304 310 316 321 Stainless Steel Round Bar 2mm 3mm 6mm Metal Rod
Product Description
The two most commonly used stainless steels 304 and 316 (or 1.4308 and 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 thread. Remember that in order to prevent the thread from being seized at high temperature, 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 material (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^^). Steel can react with other substances.
