0Cr18Ni9 Stainless Steel Composition & General Corrosion Resistance

0Cr18Ni9 is one of the most widely used austenitic stainless steels specified in GB/T 4237 and GB/T 4238, corresponding closely to international Grade 304. Containing approximately 18% chromium and 8–10% nickel, it offers excellent corrosion resistance, formability, and weldability.

The grade performs reliably in atmospheric environments, fresh water, food‑processing applications, and mildly corrosive media. It is widely used in food equipment, kitchen facilities, architectural decoration, pressure vessels, and industrial piping systems. Its good cold‑forming characteristics support stamping, bending, and welding operations.

0Cr18Ni9 is available in sheets, coils, plates, tubes, and bars. As a versatile austenitic stainless steel, it remains a standard material across food, construction, chemical, and manufacturing industries.
