What is 304 Stainless Steel Sheet?
304 stainless steel sheet is made by rolling 304 stainless steel material into flat plates with specific thicknesses and dimensions. Its main components include nickel, chromium, carbon, and manganese, which provide excellent resistance to various chemical corrosives. Because 304 stainless steel sheets are lightweight and cannot be heat treated, they are widely used in industries such as food processing, pharmaceuticals, as well as in the production of equipment, machinery parts, and chemical containers.
How Many Types of 304 Stainless Steel Sheet Are There?
Based on its chemical composition, 304 stainless steel sheets are mainly divided into three types: 304, 304L, and 304H stainless steel sheets. Each type has its own unique practical features.
Standard Specifications of 304 Stainless Steel Sheet
Before choosing the common sizes of 304 stainless steel sheets, it is important to understand the available thicknesses. Most companies order based on standard specifications, as these meet the majority of application needs and help save time on bulk purchases.

304 Stainless Steel Sheet Weight Formula
The weight of each 304 stainless steel sheet varies depending on its dimensions. The general formula to calculate the weight is:
Weight = T × W × L × 7.93
Where:
-
T = Thickness (mm)
-
W = Width (mm)
-
L = Length (mm)
-
7.93 = Density of 304 stainless steel (7.93 g/cm³)
| Comparison Items | 200 Series (201) | 300 Series (304 as a representative) | 400 Series (430 as a representative) |
|---|---|---|---|
| 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 |
| Tensile Strength (MPa) | ≥520 | ≥515 | ≥450 |
| 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 |
