What is the difference between stainless steel 316 and stainless steel 304?

The practical naked eye can't see the difference between 304 and 316 stainless steel. Many people see these numbers on the fog. Let's take a look at the difference between stainless steel 304 and 316.

      First of all, 316 stainless steel contains Mo, which is better than 304 stainless steel in high temperature environment, so in high temperature environment, engineers generally choose 316 material parts.

      Secondly, there are differences between the two brands; 304 stainless steel corresponds to the Chinese brand 0Cr18Ni9; 316 stainless steel corresponds to the Chinese brand 0Cr17Ni12Mo2.

      Third, 316 mainly reduces the Cr content and increases the Ni content and increases Mo2% to 3%. Therefore, its corrosion resistance is stronger than 304, suitable for use in chemical, seawater and other environments. Similarly, the cost of 316 is also higher than 304. Generally, 316 is used in places where the requirements are relatively high, instead of 304.

      Its practical naked eye can not see the difference between stainless steel 304 and 316, there is a more intuitive way to distinguish, using stainless steel potion for identification.
