304 is the grade of stainless steel, the American name. Its Chinese grade name is 06Cr19Ni10. Is 304 stainless steel the same as food grade 304 stainless steel? Not the same! Food grade and grade belong to two systems, but they are inextricably linked. In the national standard GB9684-2011 "National Standard for Food Safety Stainless Steel Products", the grade requirement is cancelled, and only the precipitates of heavy metals are required. Therefore, the stainless steel used in today's tableware does not require grades, but at the same time, as long as it can reach food grade , it can reach at least the level of 304 stainless steel.
