What is 202 Stainless Steel?
202 stainless steel (UNS S20200) is a chromium-manganese-nickel austenitic stainless steel designed to balance cost and performance. With 17–19% chromium, 4–6% nickel, and 7.5–10% manganese, it offers moderate corrosion resistance and excellent formability, making it ideal for decorative and industrial uses. Huaxiao-Alloy supplies 202 stainless steel in compliance with ASTM A240, JIS SUS202, and GB/T 3280 standards.

Chemical Composition of 202 stainless steel
202 stainless steel’s cost-efficiency stems from its optimized chemistry:
| Element | Content (%) | Role |
|---|---|---|
| Chromium (Cr) | 17.0–19.0 | Provides basic corrosion resistance. |
| Nickel (Ni) | 4.0–6.0 | Enhances austenitic structure. |
| Manganese (Mn) | 7.5–10.0 | Replaces nickel to reduce costs. |
| Carbon (C) | ≤0.15 | Increases hardness and strength. |
| Silicon (Si) | ≤1.0 | Deoxidizer during smelting. |
| Phosphorus (P) | ≤0.06 | Controls brittleness. |
| Sulfur (S) | ≤0.03 | Improves machinability. |
| Nitrogen (N) | ≤0.25 | Stabilizes austenitic structure. |
| Iron (Fe) | Balance | Base metal. |
Complies with ASTM A240, JIS SUS202, and GB/T 3280 standards.
Mechanical Properties of 202 stainless steel
202 stainless steel offers a balance of strength and formability:
| Property | Value |
|---|---|
| Tensile Strength | 517–827 MPa |
| Yield Strength (0.2% offset) | 276 MPa (min) |
| Elongation (50mm gauge) | 40% (min) |
| Hardness (Brinell) | 241 HB (max) |
| Modulus of Elasticity | 200 GPa |
Note: Cold working enhances strength but reduces ductility.

202 is more cost-effective for indoor or low-corrosion applications like decorative trims and appliances.
It resists rust in dry environments but may corrode in coastal or high-humidity areas. Regular cleaning is recommended.
Yes, but post-weld annealing is advised to restore corrosion resistance in welded areas.
Options include 2B (cold-rolled), BA (bright annealed), No.4 (brushed), and embossed finishes.
No. Due to moderate corrosion resistance, 304 or 316 is preferred for food contact.
