1. Overview of 316 Stainless Steel Sheets
316 stainless steel sheets are flat-rolled products made from austenitic stainless steel containing molybdenum (Mo). They excel in corrosion resistance, especially in chloride and acidic environments, making them ideal for demanding industrial applications.
2. Key Properties
Chemical Composition (ASTM A240 Standard)
| Element | Content (%) | Function |
|---|---|---|
| Chromium (Cr) | 16.0–18.0 | Forms a passive oxide layer for corrosion resistance. |
| Nickel (Ni) | 10.0–14.0 | Stabilizes austenitic structure, improves ductility. |
| Molybdenum (Mo) | 2.0–3.0 | Enhances pitting/crevice corrosion resistance. |
| Carbon (C) | ≤0.08 (≤0.03 for 316L) | Low carbon minimizes carbide precipitation during welding. |
Mechanical Properties
| Property | Value |
|---|---|
| Tensile Strength | 515–690 MPa |
| Yield Strength (0.2% Offset) | ≥205 MPa |
| Elongation (50mm Gauge) | ≥40% |
| Hardness (Rockwell B) | ≤95 HRB |
| Density | 8.0 g/cm³ |
3. Common Grades & Variants
| Grade | UNS Designation | Features | Typical Use Cases |
|---|---|---|---|
| 316 | S31600 | Standard grade, 0.08% max carbon. | General industrial equipment. |

6. Comparison with 304 Stainless Steel Sheets
| Aspect | 316 | 304 |
|---|---|---|
| Mo Content | 2–3% | 0% |
| Corrosion Resistance | Superior in chlorides | Moderate |
| Cost | 20–40% higher | Lower |
| High-Temperature Use | Up to 800°C | Up to 650°C |
7. Machining & Fabrication Tips
Cutting
-
Laser/Plasma Cutting: Use nitrogen assist gas to minimize oxidation.
-
Shearing: Ensure blade clearance ≤10% of sheet thickness.
Welding
-
Filler Material: Use ER316L for 316/316L sheets.
-
Technique: TIG welding for precision; post-weld annealing recommended for critical applications.
Forming
-
Bending Radius: ≥1x thickness for 90° bends (annealed sheets).
-
Deep Drawing: Use 316L with ≥60% elongation.
8. International Standards
| Standard | Equivalent Grades |
|---|---|
| ASTM (USA) | 316 (A240), 316L (A480) |
| EN (Europe) | 1.4401 (316), 1.4404 (316L) |
| JIS (Japan) | SUS316, SUS316L |
9. Cost-Saving Strategies
Why Choose 316 Stainless Steel Sheets?
Ideal for environments demanding corrosion resistance, hygiene, and durability, 316 sheets bridge performance and longevity. From marine engineering to cutting-edge medical devices, they deliver unmatched reliability. For non-corrosive or budget-sensitive projects, consider 304 stainless steel as a cost-effective alternative.
-
Optimize Thickness: Use thinner sheets (e.g., 2mm vs. 3mm) where structurally feasible.
-
Local Sourcing: Chinese mills (e.g., TISCO, Baosteel) offer competitive pricing.
-
Recycled Content: Specify 70%+ recycled 316 scrap to reduce costs by ~15%.
