EN 1.4539 / 904L Stainless Steel Plate & Sheets – 4×8 ft (1.2×2.4 m) & 1.5×6 m Sizes – Supplied with EN 10204 3.1 Mill Test Certificate
Product Overview
We supply high-quality EN 1.4539 (UNS N08904, commonly known as 904L) stainless steel plates and sheets in standard and custom dimensions—including 4×8 feet (1.2×2.4 meters) and 1.5×6 meters—ideal for demanding applications in the chemical processing, pharmaceutical, oil & gas, marine, and pollution control industries. All material is manufactured to meet stringent international standards and is delivered with a full EN 10204 3.1 Mill Test Certificate, ensuring complete traceability, chemical compliance, and mechanical verification.
904L is a super austenitic stainless steel distinguished by its exceptional resistance to corrosion—particularly in acidic, chloride-rich, and reducing environments—thanks to its high alloy content of chromium, nickel, molybdenum, and copper.
Key Advantages of 904L (EN 1.4539)
- ✅ Outstanding corrosion resistance in sulfuric, phosphoric, acetic, and formic acids
- ✅ High resistance to pitting and crevice corrosion (PREN ≥ 34)
- ✅ Non-magnetic and weldable without post-weld heat treatment
- ✅ Excellent performance in seawater and flue gas desulfurization (FGD) systems
- ✅ Low carbon content (<0.02%) prevents sensitization during welding
- ✅ Fully compliant with ASTM A240, ASME SA-240, EN 10028-7, and ISO 9328-7
Available Dimensions & Tolerances
| Parameter | Standard Options | Custom Options Available |
|---|---|---|
| Thickness | 1.5 mm – 50.0 mm | Yes |
| Sheet Size | 4 ft × 8 ft (1219 mm × 2438 mm) | Up to 2500×6000 mm |
| Plate Size | 1500 mm × 6000 mm | As per project drawing |
| Surface Finish | Hot-rolled annealed & pickled (HRAP), 2B, or blasted | Optional polishing (e.g., No.4) |
| Tolerance (Thickness) | ±0.15 mm (≤10 mm); ±1% (>10 mm) | Per EN 10029 / ASTM A480 |
Note: 4×8 ft sheets are typically stocked in thinner gauges (1.5–12 mm), while thicker plates (12–50 mm) are commonly supplied in 1.5×6 m or cut-to-size.
Chemical Composition (EN 1.4539 / UNS N08904)
| Element | C | Si | Mn | P | S | Cr | Ni | Mo | Cu | N |
|---|---|---|---|---|---|---|---|---|---|---|
| Max/Min | ≤0.02 | ≤1.00 | ≤2.00 | ≤0.045 | ≤0.035 | 19.0–23.0 | 23.0–28.0 | 4.0–5.0 | 1.0–2.0 | ≤0.10 |
This composition delivers superior resistance to uniform and localized corrosion, especially in environments where 316L or duplex steels would fail.
Mechanical Properties (Typical at 20°C)
| Property | Minimum Value |
|---|---|
| Tensile Strength (Rm) | 490 MPa |
| Yield Strength (Rp0.2) | 220 MPa |
| Elongation (A5) | 35% |
| Hardness (HBW) | ≤220 |
| Density | 7.95 g/cm³ |
These properties ensure structural integrity under load while maintaining excellent ductility for forming and fabrication.
EN 10204 3.1 Mill Test Certificate – What It Includes
Every shipment includes an EN 10204 Type 3.1 certificate, issued by the manufacturer’s authorized quality representative, containing:
- Heat number and full traceability
- Actual chemical analysis (per element)
- Verified mechanical test results
- Compliance statement with EN 10028-7 / ASTM A240
- Signature and stamp from QA department
This documentation is essential for pressure equipment (PED 2014/68/EU), ASME projects, and quality audits in regulated industries.
Common Industrial Applications
| Industry | Typical Use Cases |
|---|---|
| Chemical Processing | Reactors, acid storage tanks, piping, pumps handling H₂SO₄ |
| Pharmaceutical | Sterile vessels, mixing tanks, fluid transfer systems |
| Oil & Gas | Downstream processing units, sour service components |
| Marine & Offshore | Seawater intake systems, desalination plants, subsea hardware |
| Environmental | Flue gas scrubbers, wastewater treatment tanks |
904L is often specified where long service life, minimal maintenance, and safety-critical reliability are non-negotiable.
Fabrication & Machining Guidance
- Cutting: Excellent for laser, plasma, and waterjet cutting. Fiber lasers yield clean edges up to 25 mm thickness.
- Welding: Use ER385 or E385-16 filler. No preheat required; interpass temperature <100°C recommended.
- Forming: Good cold-forming capability; springback should be accounted for in tooling design.
- Machining: Slower speeds and rigid setups advised due to work-hardening tendency. Use carbide tools and ample coolant.
Packaging & Delivery
- Plates/sheets protected with anti-rust paper and PVC film
- Bundled on wooden pallets with edge protectors
- Export-ready packaging compliant with ISO 8377
- Global shipping via sea or air freight
- Lead time: 2–4 weeks (stock items may ship in 5–7 days)
