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

Second
There are differences between the two on the grade;
There are differences between the two on the grade;
304 stainless steel corresponds to Chinese grade 0Cr18Ni9; 316 stainless steel corresponds to Chinese grade 0Cr17Ni12Mo2
Third
316 mainly reduces the Cr content and increases the Ni content and increases Mo2% to 3%.
316 mainly reduces the Cr content and increases the Ni content and increases Mo2% to 3%.
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.
The difference between stainless steel 304 and 316 can not be seen with the naked eye. There is also a more intuitive method of identification. Use stainless steel syrup for identification. For the use of stainless steel syrup, please click here.
