The difference between stainless steel 304 and 316

In fact, it is impossible to see the difference between 304 and 316 stainless steel with the naked eye. Many people are confused when they see these numbers. Let me take a look at the difference between stainless steel 304 and 316 today.
      First of all, 316 stainless steel contains Mo, which has better corrosion resistance than 304 stainless steel in high temperature environment. Therefore, in high temperature environment, engineers generally choose parts made of 316 material.
      Secondly, there are also differences between the two in terms of grades; 304 stainless steel corresponds to the Chinese grade 0Cr18Ni9; 316 stainless steel corresponds to the Chinese grade 0Cr17Ni12Mo2.
      Third, 316 mainly reduces the Cr content and increases the Ni content and increases the Mo2%~3%. Therefore, its corrosion resistance is stronger than that of 304, and it is suitable for use in chemical, seawater and other environments. Similarly, the cost of 316 is also higher than that of 304. Generally, 316 is used in places with higher requirements to replace 304.
      In fact, it is impossible to see the difference between stainless steel 304 and 316 with the naked eye. There is also a more intuitive identification method, which is to use stainless steel potion for identification.
