What is the difference between 304 and 306 stainless steel plates

Posted by:Rain Time:2019.12.04 01:13

First of all, 316 stainless steel contains Mo, which has better corrosion resistance than 304 stainless steel in high temperature environment. Therefore, engineers generally choose 316 material parts in high temperature environment.

Second, there are differences between the two; 304 stainless steel corresponds to 0Cr18Ni9, 316 stainless steel corresponds to  0Cr17Ni12Mo2.

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

The practical naked eye cannot see the difference between stainless steel 304 and 316 at all. There is also a more intuitive method of identification, using stainless steel potion for identification.
