The corrosion resistance and value of 304 steel depends largely on its composition, which includes important elements such as nickel (Ni) and chromium (Cr). Specific requirements for Type 304 steel are outlined in product standards. It is generally believed in the industry that as long as the Ni content is above 8% and the Cr content is above 18%, it can be classified as 304 steel. That's why it's commonly known as 18/8 stainless steel. It is worth noting that the relevant product standards of 304 steel have clear regulations, which may vary according to the shape and form of stainless steel.
