The difference between the national standard 304 stainless steel and the American standard 304 stainless steel primarily lies in the elemental content.
The national standard 304 stainless steel contains 8% nickel and over 18% chromium, while the American standard 304 stainless steel contains 9% nickel and over 19% chromium.
Additionally, the carbon and phosphorus content in the foreign standard 304 stainless steel is lower compared to the American standard 304 stainless steel.
Supplementary Information:
Stainless steel is a shorthand for corrosion-resistant and acid-proof steel. It refers to steel grades that resist corrosion from air, steam, water, and other mild corrosive media, or steel grades that possess corrosion resistance. In contrast, acid-proof steel is the term for steel grades that can withstand corrosion from chemical media (acids, alkalis, salts, etc.).
