|---|---|---|---|
| Chemical Composition | Chromium (Cr) 16% – 18%, manganese (Mn) 5.5% – 7.5%, nickel (Ni) 3.5% – 5.5%, nitrogen (N) ≤0.25% | Chromium (Cr) 18% – 20%, nickel (Ni) 8% – 10.5%, low carbon | Chromium (Cr) 16% – 18%, low carbon, ferrite structure |

| Elongation (%) | ≥40 | ≥40 | ≥22 |
| Corrosion Resistance | Moderate corrosion resistance, suitable for less corrosive environments. Prone to rusting in humid or corrosive conditions compared to 300 series. | Good general corrosion resistance, suitable for general atmosphere, fresh water and other environments, relatively weak tolerance to chloride ions | Fair corrosion resistance, better than carbon steel but inferior to 300 series. Susceptible to pitting corrosion in chloride-rich environments. |
| Magnetic Properties | Weakly magnetic due to its alloy composition | Non-magnetic in the annealed state, may become slightly magnetic under certain processing conditions | Magnetic |
| Cost | Relatively low, due to lower nickel content and relatively simple composition | Moderate, as a widely used and reliable grade | Relatively low, similar to 200 series in terms of cost, but with different performance characteristics |
| Application Fields | Interior decoration, low-end kitchenware, some decorative trims in buildings where corrosion resistance requirements are not high | Kitchen utensils, building decoration, general industrial components and other daily fields | Appliance housings, automotive trim, some food processing equipment where non-magnetic properties are not required and moderate corrosion resistance suffices |
