Material Science Guide – 304 Stainless Steel
When shopping at building‑material markets, selecting kitchenware or custom‑made hardware, nearly everyone has heard of 304 stainless steel. Yet 90% of people do not know: 304 is only a common name, not the official grade designated by China’s national standard. Under Chinese national standards, the sole official, formal and valid new grade for genuine 304 stainless steel is “06Cr19Ni10”.
