bg4.png 【Discussion Thread 50】Differences between 304——S304——SS304——SUS304——S30408——304SS, etc. There are so many different names; it’s possible that not all of them have been listed. Could any member of the community explain this clearly?
The material explains it clearly; what’s discussed is how to use it?
304: the common name in China is SUS304; according to Japanese standards it is SS304, while in the United States it is referred to as S30408. In China, the numerical designation for 304 is also used
These stainless steel codes are merely different ways in which **or various organizations identify 304 stainless steel; its elemental composition remains essentially the same.
Just select materials in accordance with the relevant standard specifications!
Though called differently, it actually refers to 18-8 stainless steel
Are there some differences in the element contents? Is there any difference in the processing methods? Does the imported steel plate need to be retested? I remember that stainless steel flat sheets need to be re-inspected.

Due to different standards used, there are slight differences among the elements
I want to know what the difference is between 304 and 30408
Sometimes we specify S30408 for stressed components, and 304 for unstressed components (except for tower shells and those with high requirements)
