There are three main differences between S30408 stainless steel and 304 stainless steel:
The UNS numeric code for S30408 is 06Cr19Ni10, while the UNS numeric code for 304 is S30400;
The chemical composition of S30408 differs from 304 in terms of carbon (C), phosphorus (P), sulfur (S) and chromium (Cr) content;
The mechanical properties of S30408 and 304 are slightly different, specifically in terms of yield strength.
So which is better – S30408 or 304? And what are the differences between them? It is important to consider the safety of using these materials in food applications. I will delve into these three points in more detail.
