Excerpt:
Molybdenum-bearing low-carbon stainless plate for corrosion-conscious fabrication, tanks, process equipment and cut components. Compared with 304, molybdenum supports improved pitting resistance in many environments, but 316L is not immune to chloride attack. Selection depends on temperature, chloride level, cleaning and fabrication detail.

316L Hot Rolled Stainless Steel Plate
Molybdenum-bearing low-carbon stainless plate for corrosion-conscious fabrication, tanks, process equipment and cut components. Compared with 304, molybdenum supports improved pitting resistance in many environments, but 316L is not immune to chloride attack. Selection depends on temperature, chloride level, cleaning and fabrication detail.
| Ordering item | Specification |
|---|---|
| Material / standard | ASTM A240/A240M, UNS S31603 |
| Product family | Steel Plates |
| Supply basis | Enquiry-based grade, dimensions, processing and quantity; availability, MOQ and delivery confirmed in the quotation. |
| Inspection documents | Request heat/batch records and EN 10204 3.1 or other documents where required; actual document scope must be confirmed. |
01 / Selection Advantages
- Low-carbon chemistry helps control sensitization risk during appropriate welding procedures.
- Plate and cut-part enquiries can be reviewed together to improve nesting and material identification.
- Surface protection, flatness and cutting allowance can be aligned with the downstream fabrication process.
02 / Specifications & Size Schedule
Use the following options to prepare a complete enquiry. The lists do not imply that every dimension combination is stocked or interchangeable with another standard. State the required tolerances and quantity for each line.
| Parameter | Enquiry requirement |
|---|---|
| Thickness / mm | 3, 4, 5, 6, 8, 10, 12, 16, 20, 25, 30, 40, 50 |
| Width / mm | 1000, 1250, 1500, 2000; heavier/wider plates by enquiry |
| Length / mm | 2000, 2500, 3000, 6000 or drawing-based cuts |
| Finish | Hot rolled, annealed and pickled / No.1 as agreed |
| Edges | Mill, sheared, sawn or thermal cut; state allowance and edge acceptance |
| Thickness / mm | Theoretical kg/m² | 1500 × 6000 mm plate / kg |
|---|---|---|
| 3 | 24.09 | 216.8 |
| 4 | 32.12 | 289.1 |
| 5 | 40.15 | 361.3 |
| 6 | 48.18 | 433.6 |
| 8 | 64.24 | 578.2 |
| 10 | 80.30 | 722.7 |
| 12 | 96.36 | 867.2 |
| 16 | 128.48 | 1156.3 |

| 50 | 401.50 | 3613.5 |
03 / Chemical Composition
Composition is expressed in weight percent. Maximum and minimum limits refer to the listed grade/product reference; final acceptance follows the agreed standard edition and heat analysis.
| Element | Grade reference / wt.% |
|---|---|
| C | ≤0.030 |
| Mn | ≤2.00 |
| P | ≤0.045 |
| S | ≤0.030 |
| Si | ≤0.75 |
| Cr | 16.0–18.0 |
| Ni | 10.0–14.0 |
| Mo | 2.0–3.0 |
| N | ≤0.10 |
| Fe | Balance |
04 / Mechanical Properties & Technical Notes
| Condition | Min tensile / MPa | Min proof / MPa | Elongation / hardness |
|---|---|---|---|
| Annealed plate reference | 485 | 170 | ≥40%; ≤95 HRB |
Mass is calculated at 8.03 g/cm³ and nominal dimensions, excluding tolerances and packing. Heavy thicknesses and specimen locations require the agreed standard provisions. Surface grinding and thermal cutting affect the finished-part acceptance plan.
05 / Processing & Inspection
| Control point | What to agree or inspect |
|---|---|
| Analysis | Verify Cr, Ni, Mo and low carbon with heat-linked documents. |
| Plate acceptance | Review thickness, flatness, surface, edge quality and heat identification. |
| Cutting | Agree kerf, heat-affected edge removal, nesting and part-number transfer. |
| Further checks | Specify UT, PMI or third-party witness requirements at quotation. |
Include additional tests, third-party inspection, marking transfer and processing requirements before order confirmation. Qida can coordinate the agreed inspection scope and supporting records; an online product guide is not a delivered-batch test certificate.
06 / Export Packaging & Transport
| Packing item | Practical requirement |
|---|---|
| Pallet support | Use suitable bearers and edge protection to prevent sagging and strap marks. |
| Surface care | Clean interleaving or protective film where agreed; avoid contamination. |
| Water protection | Use transit-appropriate wrapping without sealing in condensation. |
| Marks | Keep parent heat and cut-part identifiers linked to the packing list. |
Agree destination port, Incoterms rule and named place, package mass, unloading equipment and required shipping documents. Container capacity depends on payload limits, route and load distribution. For regulated solid-wood packaging, confirm the applicable ISPM 15 treatment and marking requirements.
07 / Qida Procurement Support
| Order stage | Our coordination | Buyer benefit |
|---|---|---|
| Specification review | Review material, dimensions, units, drawings and destination requirements. | A clear line-by-line enquiry helps reduce omissions and incompatible substitutions. |
| Processing plan | Confirm cutting, finishing, inspection and identification items in writing. | The buyer can assess scope and acceptance before production or sourcing proceeds. |
| Packing & dispatch | Coordinate labels, packing list, suitable protection and shipping-document requirements. | Piece count and heat/lot correspondence can be checked at agreed milestones. |
| After-sales follow-up | Review order references, arrival photos and inspection records for reported issues. | A documented issue description supports a specific response and follow-up. |
08 / Request a Detailed Quotation
Send the standard and edition, grade, size schedule, quantity per size, material condition, finish, processing drawings, tests/documents, packing requirements and destination port. Include maximum piece or package weight and any project approval requirements. Pricing, minimum quantity and lead time will be confirmed against the actual requirement.
