2000mm Width 304 / 304L Stainless Steel Plate – Thickness 3.0–40.0mm Industrial-Grade SS Plate for Demanding Applications
Overview
The 2000mm width 304 / 304L stainless steel plate is a premium-grade, wide-format flat-rolled product engineered for industrial applications that demand exceptional corrosion resistance, mechanical strength, and dimensional stability. With thicknesses ranging from 3.0 mm to 40.0 mm, this plate offers unmatched versatility across sectors such as chemical processing, food & beverage, pharmaceuticals, oil & gas, cryogenic systems (e.g., LNG pipelines), power generation, and heavy machinery fabrication.
Manufactured to meet international standards—including ASTM A240, ASME SA240, GB/T 24511-2009, and EN 10088—our 2000mm-wide plates are produced using advanced hot-rolling and controlled annealing techniques to ensure uniform microstructure, superior surface finish, and consistent mechanical properties across the entire sheet.
The availability of both 304 (UNS S30400) and 304L (UNS S30403) variants allows customers to select the optimal grade based on welding requirements and service environment. While standard 304 offers excellent general-purpose performance, 304L—with its ultra-low carbon content (<0.03%)—provides enhanced resistance to intergranular corrosion, especially in welded structures where post-weld heat treatment is impractical.
Key Advantages of 2000mm Wide 304/304L Plates
- Wide Format Efficiency: The 2000mm (≈78.7 inches) width minimizes the need for seam welding in large fabrications, reducing labor costs and improving structural integrity.
- Broad Thickness Range: From thin 3.0mm sheets for cladding and ductwork to robust 40.0mm plates for pressure vessels and structural supports.
- Superior Corrosion Resistance: Excellent performance in oxidizing environments, mild acids, alkalis, and atmospheric exposure.
- Weldability & Formability: Both grades are readily weldable by all standard methods; 304L is preferred for heavy-section welding.
- Cryogenic Toughness: Maintains ductility and impact strength at temperatures as low as -196°C (liquid nitrogen), making it ideal for LNG and cryogenic transport systems.
- Hygienic Surface Options: Available in finishes like 2B, No.1, BA, No.4 (brushed), and custom textures for sanitary or aesthetic applications.

Why Choose 2000mm Width?
Standard stainless steel plates are often limited to 1219mm or 1500mm widths. Our 2000mm-wide plates offer significant advantages:
- Reduced Welding Joints: Fewer seams mean lower fabrication time, reduced risk of leakage, and improved aesthetics.
- Higher Material Utilization: Optimized nesting for laser cutting or plasma profiling reduces scrap.
- Structural Continuity: Ideal for large-diameter rolled cylinders (e.g., pressure vessels) without longitudinal welds.
- Logistical Efficiency: Fewer pieces to handle, ship, and inventory.
Recent breakthroughs—such as those achieved by Hongxing Hongbo New Materials—have enabled stable rolling of 40mm-thick S30403 plates at 2000mm+ widths, overcoming challenges like edge cracking, thickness variation, and surface defects through precision temperature control and advanced mill automation.
Quality Assurance & Traceability
Every batch undergoes rigorous quality control:
- Spectrometric analysis for chemical composition
- Ultrasonic testing (UT) for internal defects (optional for critical applications)
- Tensile and hardness testing
- Surface inspection under controlled lighting
- Full traceability via heat number and production log
We provide mill test reports (MTRs) with each shipment, ensuring compliance with project specifications and regulatory requirements.
Packaging & Delivery
Plates are carefully packaged to prevent surface damage during transit:
- Interleaved with PVC film or paper
- Bundled with steel straps
- Wooden pallets or cradles for thick plates (>20mm)
- Export-standard fumigated wooden cases (upon request)
Lead time: 7–15 days for standard sizes; 20–30 days for custom dimensions or certified orders.
Frequently Asked Questions (FAQ)
Q: What’s the difference between 304 and 304L?
A: 304L has lower carbon content (<0.03% vs. ≤0.08%), which prevents chromium carbide precipitation during welding, thus avoiding intergranular corrosion. Use 304L for welded structures >6mm thick or when post-weld annealing isn’t feasible.

Q: Can I get 2000mm-wide plates in 40mm thickness?
A: Yes. Advanced rolling mills now produce 40mm-thick 304/304L plates at 2000mm width with excellent flatness and uniform properties—ideal for heavy industrial use.
