The difference between 304 and 316 stainless steel
It is practically 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 look at the difference between stainless steel 304 and 316 today.
First, 316 stainless steel contains Mo, which has better corrosion resistance in high-temperature environments than 304 stainless steel. Therefore, in high-temperature environments, engineers generally choose 316 material parts.
Secondly, there are differences between the two in terms of grades; 304 stainless steel corresponds to Chinese grade 0Cr18Ni9; 316 stainless steel corresponds to Chinese grade 0Cr17Ni12Mo2.
Third, 316 mainly reduces the Cr content, increases the Ni content, and increases Mo 2%~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.
It is practically impossible to see the difference between stainless steel 304 and 316 with the naked eye. There is a more intuitive way to distinguish, using stainless steel potion for identification.
