Whether you need standard finishing or mirror-like 8K polish, we deliver plates that meet strict international standards.
Product Overview & Key Features
Our stainless steel plates are manufactured using advanced hot rolling and cold rolling processes, ensuring precise thickness tolerance and excellent surface quality. Available in multiple grades (304, 316L, 317, and 2205 Duplex), these plates combine high strength with superior corrosion resistance, making them ideal for demanding environments.
Material Grades: Choose from 304 (general-purpose), 316L (enhanced corrosion resistance for chemical & marine), 317 (higher molybdenum content for aggressive chemicals), and 2205 duplex (high strength & excellent stress corrosion cracking resistance).
Surface Finishes: 2B (matte, cold-rolled), BA (bright annealed, reflective), and 8K (mirror finish) – all customizable per your requirements.
Standard Dimensions: 4x8 feet (1220mm x 2440mm) – the most common size for fabrication. Other sizes available upon request.
Thickness Range: from 0.5mm up to 120mm, suitable for light panels or heavy structural plates.
Processing Options: Hot rolled or cold rolled, with either mill edge, slit edge, or deburred edge.
Technical Specifications (Typical Values)
| Parameter | 304 | 316L | 317 | 2205 Duplex |
|---|---|---|---|---|
| Tensile Strength (MPa) | ≥520 | ≥485 | ≥550 | ≥620 |
| Yield Strength (MPa) | ≥205 | ≥170 | ≥205 | ≥450 |
| Elongation (%) | ≥40 | ≥40 | ≥35 | ≥25 |

Advantages & Customer Benefits
Corrosion Resistance: 316L and 317 grades offer excellent resistance to chlorides, acids, and aggressive media, while 2205 duplex resists pitting and crevice corrosion under harsh conditions.
Strength & Durability: Duplex 2205 provides nearly double the yield strength of standard austenitic grades, reducing material thickness and weight – saving costs without compromising performance.
Versatile Finishes: 2B for general forming, BA for aesthetic interior panels, and 8K mirror for decorative or hygienic surfaces (e.g., kitchen backsplashes, elevators).
Customizable: We offer custom cutting, bending, and surface treatment options to meet your specific project needs.
Consistent Quality: All plates are tested for mechanical properties and chemical composition, ensuring conformity to ASTM and international standards.

Frequently Asked Questions (FAQ)
What is the difference between 304 and 316L stainless steel plates?
316L contains molybdenum (2-3%) which provides superior corrosion resistance against chlorides, acids, and marine environments. 304 is more cost-effective for general applications.Can I get a mirror (8K) finish on both sides?
Yes, we offer single-side or double-side mirror finish upon request. Please specify your requirement when ordering.What thickness tolerances do you guarantee?
We follow ASTM A480 standards: for thickness ≤ 4.75mm, tolerance is ±0.13mm; for thickness 4.75-10mm, tolerance is ±0.15mm; for thicker plates, tolerances are per industry standards, and we can provide detailed charts upon request.Is 2205 duplex stainless steel weldable?
Yes, 2205 can be welded using standard techniques (GTAW, SMAW, SAW) with appropriate filler metals like ER2209. Preheating is not required, but interpass temperature should be controlled below 300°F (150°C).What are the typical lead times for 4x8 plates?
For standard finishes and thicknesses, lead time is approximately 10-15 business days. For custom orders or large quantities, please consult our sales team for accurate scheduling.Do you provide cutting and bending services?
Yes, we offer plasma cutting, laser cutting, shearing, and bending services. Contact us with your drawings to discuss capabilities.Can you supply test certificates with the plates?
Absolutely. We can issue mill test certificates (MTC) in accordance with EN 10204 3.1 or 3.2, and also provide third-party inspection reports if required.Do you export to my country?
We ship to North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East. Our logistics network covers most global ports – please inquire for specific destinations.
