In the field of stainless steel, we often hear the names SUS304, 304 and 06Cr19Ni10. Although they each have a different logo, they actually refer to the same stainless steel material.

First, we need to understand what each name stands for. SUS is the abbreviation of the Japanese Material Standard, so SUS304 is a stainless steel defined in accordance with the Japanese standard. And 304 is a stainless steel grade produced in accordance with the American ASTM standard. As for 06Cr19Ni10, this is the Chinese national standard for the same kind of stainless steel named.

So why do they point to the same stainless steel? This is mainly due to the fact that when various countries develop their own stainless steel standards, they will classify different types of stainless steel based on the proportion of iron, chromium, nickel and other elements. The numerical parts of SUS304, 304 and 06Cr19Ni10 all represent the proportion of chromium and nickel content. Specifically, the "30" in the number 304 refers to the percentage content of chromium, and the "4" refers to the percentage content of nickel. Similarly, the "06" in 06Cr19Ni10 refers to the percentage content of iron, "19" refers to the percentage content of chromium, and "10" refers to the percentage content of nickel. Since these numbers point to the same stainless steel composition in various standards, we can say that SUS304, 304 and 06Cr19Ni10 actually refer to the same stainless steel material.

Although they are marked differently, SUS304, 304 and 06Cr19Ni10 are the same stainless steel material, whether according to Japanese standards, American standards or Chinese standards. This provides convenience for the international trade and exchange of stainless steel, and also proves that the global standardization process of stainless steel is constantly advancing.
