|---|---|---|
| Product Name | 201 Stainless Steel Sheet | Flat-rolled austenitic stainless steel sheet product |
| Material Grade | AISI 201 / EN 1.4372 / JIS SUS201 / GB 12Cr17Mn6Ni5N | Manganese-substituted austenitic stainless steel, lower nickel content than 304 |
| Standard Compliance | ASTM A240/A240M, EN 10088-2, JIS G4304, GB/T 3280 | Meets international flat-rolled stainless steel product standards |
| Chemical Composition – Cr | 16.00–18.00% | Chromium content providing corrosion resistance |
| Chemical Composition – Ni | 3.50–5.50% | Reduced nickel vs. 304; partially replaced by manganese |
| Chemical Composition – Mn | 5.50–7.50% | High manganese stabilizes austenite structure |
| Chemical Composition – C / Si / N | C ≤0.15%, Si ≤1.00%, N ≤0.25% | Carbon kept low for weldability; nitrogen enhances strength |
| Tensile Strength | ≥515 MPa (≥75 ksi) | Per ASTM A240; typical value 620–800 MPa in practice |
| Yield Strength | ≥275 MPa (≥40 ksi) | 0.2% proof stress per ASTM A240 |
| Elongation | ≥40% | Minimum elongation in 50 mm gauge length per ASTM A240 |
| Hardness | ≤241 HBW / ≤96 HRB | Brinell and Rockwell B hardness limits per ASTM A240 |
| Thickness Range | 0.3 mm – 14.0 mm | Thinner gauges available as cold-rolled; thicker as hot-rolled |
| Width × Length | Width: 600–2000 mm; Length: 1000–6000 mm (custom available) | Standard coil and cut-to-length sheet dimensions |
| Surface Finish | No.1, 2B, BA, No.4, HL, Mirror (No.8) | 2B most common for general use; BA/HL/Mirror for decorative applications |
| Application | Kitchen equipment, decorative panels, elevator panels, automotive trim, storage tanks, signage | Suitable for indoor and mildly corrosive environments |
| Certification | ISO 9001, Mill Test Certificate (MTC) per EN 10204 3.1/3.2 | Third-party inspection available upon request |
| Packaging | Wooden pallet with waterproof paper and steel strip binding; coil on steel mandrel | Export-standard seaworthy packaging to prevent transit damage |
| MOQ | 1 Metric Ton (MT) | Mixed specifications accepted; spot stock available for small orders |
Initial thickness variation resolved after supplier intervention
Our first order of 201 sheets at 0.6mm for automotive interior trim components showed thickness variation of ±0.08mm on roughly 15 sheets out of 200, slightly outside our agreed tolerance. We raised this with the supplier immediately. To their credit, replacement sheets were dispatched within 4 business days and a revised QC checklist was shared for future orders. ASTM A240 certification and MTR were provided throughout. The resolution was handled professionally. We have since placed a follow-up order and quality on that batch was fully within specification.
