304L vs 304 Stainless Steel Plate
| products |
|
|
| Parameter | 304L Stainless Steel Plate | 304 Stainless Steel Plate |
| Carbon Content | ≤0.03% (Low Carbon) | ≤0.08% (Standard) |
| Weldability | Excellent; no post-weld heat treatment needed | Good; requires post-weld annealing to prevent corrosion |
| Intergranular Corrosion Resistance | Superior (no carbide precipitation) | Good (risk after welding) |
| Tensile Strength | ≥485 MPa | ≥515 MPa |
| Yield Strength | ≥170 MPa | ≥205 MPa |
| Price | 5–10% higher than 304 | Standard grade, lower cost |
| Best For | Welded structures, chemical equipment, high-corrosion zones | General fabrication, non-welded parts, cost-sensitive projects |
