What is 201 Stainless Steel Sheet?
201 stainless steel sheet is an alloy steel flat sheet used in both industrial and residential applications. It is known for its excellent hardness due to its high chromium, manganese, and nitrogen content. With a lower nickel content, 201 stainless steel offers a cost-effective alternative to other austenitic stainless steels. Under normal conditions, 201 stainless sheets offer good corrosion resistance and are widely used in structural, shipbuilding, and other high-strength-demanding applications, thanks to their weldability, formability, and cutting performance.
Let’s explore the features and specifications of 201 stainless steel sheets and how OrinoxSteel can help you succeed in your specific applications.
Characteristics of 201 Stainless Steel Sheet
201 stainless steel sheets are produced in flat sheet form from 201 grade stainless steel. Compared to other grades, it contains higher levels of manganese and nitrogen, giving it enhanced mechanical properties. It offers moderate corrosion resistance, excellent strength under cold temperatures, and great formability, making it a popular choice for structural uses with reliable quality and performance.
Common Types of 201 Stainless Steel Sheets
Based on the 201 steel standard, the sheets are typically divided into two types: 201 and 201LN, to suit various applications. This classification allows both suppliers and buyers to clearly distinguish the appropriate variant for different uses.
Available Sizes and Specifications
To select the right 201 stainless steel sheet for your project, thickness and dimensions are key. Below are some standard sizes commonly available, with custom dimensions available upon request:
Thickness Options:
-
1.0 mm
-
1.2 mm
-
1.5 mm
-
2.0 mm
-
3.0 mm
-
5.0 mm
-

Standard Dimensions (Width × Length):
-
1000 × 1200 mm
-
1219 × 2438 mm
-
1220 × 1000 mm
-
1250 × 2500 mm
-
1500 × 1000 mm
-
1500 × 3000 mm
-
1524 × 6000 mm
How to Calculate the Weight of 201 Stainless Steel Sheet
Each sheet’s weight depends on its size and thickness. The standard formula for calculating sheet weight is:
Weight (kg) = Thickness (T) × Width (W) × Length (L) × 7.93
Where:
-
T = thickness in meters
-
W = width in meters
-
L = length in meters
-
7.93 is the density of 201 stainless steel in 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 |
