1. Standard Compliance
316L stainless steel sheets/strips primarily adhere to ASTM A240/A240M-2018, which governs chromium and chromium-nickel stainless steel for pressure vessels and general applications158. This standard ensures consistent chemical composition, mechanical properties, and dimensional tolerances. Supplementary standards include:
-
JIS G4305/4313 (Japan)
-
GB/T 3280 (China)
-
DIN EN 10088-2 (Europe).
2. Chemical Composition & Key Properties
Chemical Requirements (Weight %)
| Element | Min (%) | Max (%) |
|---|---|---|
| C | - | 0.03 |
| Cr | 16.0 | 18.0 |
| Ni | 10.0 | 14.0 |
| Mo | 2.0 | 3.0 |
| Mn | - | 2.0 |
| Si | - | 0.75 |
| S | - | 0.03 |
| P | - | 0.045 |
Enhanced Corrosion Resistance:
-
Low carbon (≤0.03%) prevents sensitization (carbide precipitation at grain boundaries), enabling welding without post-annealing.
-
Molybdenum addition (2–3%) significantly improves pitting and crevice corrosion resistance in chloride-rich environments (e.g., seawater, chemical plants).
Mechanical Properties
| Property | Value |
|---|---|
| Yield Strength | ≥177 MPa |
| Tensile Strength | ≥480 MPa |
| Elongation | ≥40% |
| Hardness (max) | 187 HB |
-
Cold rolling enables higher hardness states (e.g., 1/4H, 1/2H, EH), with hardness up to HV 600.
-
Retains toughness at cryogenic temperatures (as low as –253°C), suitable for liquid hydrogen storage tanks.
3. Dimensions and Tolerances
Cold-rolled 316L strips/sheets are available in versatile dimensions:
-
Thickness: 0.03 mm (ultra-thin for electronics) to 6.0 mm.
-
Width: 10–2,000 mm (standard), with precision slitting for narrow widths (e.g., 20–610 mm).
-
Coil Parameters: Inner diameters of 200–508 mm; weights customized per tonnage requirements.
4. Surface Finishes: 2B and Beyond
-
2B Finish: Smooth, moderately reflective surface achieved by cold rolling, annealing, pickling, and light temper rolling. Standard for industrial and architectural applications.
-
Alternative Finishes:
-
BA (Bright Annealed): Mirror-like finish (6K–9K) for decorative parts.
-
No.1: Rough industrial surface for further processing.
-
Hairline/Matte: Brushed or satin textures for aesthetic components.
-
5. Equivalent Grades Across Standards
316L is globally standardized under multiple designations:
| Region | Standard | Grade |
|---|---|---|
| USA | ASTM/UNS | S31603 |
| China | GB | 022Cr17Ni12Mo2 |
| Europe | DIN/EN | 1.4435/X2CrNiMo18-14-3 |
| Japan | JIS | SUS 316L |
| Russia | GOST | 03Х17Н14М2 |
6. Major Manufacturers and Quality Assurance
