Brand
Hemaokang
Welcome to Hemaokang Steel (Shandong) Co., Ltd. – your trusted partner in high-performance stainless steel solutions. Our Duplex Stainless Steel Plate 2205 with 6mm thickness and 2500mm length is specifically engineered for demanding chemical tank applications. Combining superior strength, exceptional corrosion resistance, and excellent weldability, this plate delivers reliable performance under harsh environments. Backed by our ISO9001-certified quality management system and extensive export experience (annual export value US$50M–US$100M), we ensure every plate meets the highest industry standards.
Key Features & Technical Specifications
- Exceptional Corrosion Resistance: The duplex microstructure (austenite + ferrite) provides outstanding resistance to stress corrosion cracking, pitting, and crevice corrosion – ideal for acidic and chloride-rich chemical environments.
- High Mechanical Strength: With a minimum yield strength of 450 MPa and tensile strength up to 620 MPa, this plate offers nearly double the strength of standard austenitic stainless steels, allowing thinner wall designs and weight reduction.
- Excellent Weldability & Formability: Low carbon content and balanced composition enable easy welding without preheating, and good ductility for bending, cutting, and forming operations.
- Precise Dimensional Control: Rolled to exact 6mm thickness and 2500mm length with tight tolerances (±0.3mm thickness, ±5mm length), ensuring consistent fit in fabrication.
- Versatile Surface Options: Available in 2B (cold-rolled, bright), BA (bright annealed), or No.1 (hot-rolled, pickled) finishes to suit different aesthetic and functional requirements.
- Wide Application Range: Beyond chemical tanks, suitable for pressure vessels, heat exchangers, offshore platforms, desalination plants, and pulp & paper equipment.

-
Q: What is the minimum order quantity (MOQ) for this plate?
A: Our standard MOQ is 5 tons, but we can accommodate smaller quantities for trial orders. Please contact us for details. -
Q: Can you provide custom sizes (width/length) beyond 2500mm?
A: Yes, we offer customizable dimensions up to 12000mm length and 3000mm width, subject to production capability. Lead time may vary. -
Q: Is this plate suitable for high-temperature service?
A: Duplex 2205 is typically used up to 300°C (572°F). For higher temperatures, consider super duplex grades. We can advise based on your specific operating conditions. -
Q: What welding procedures are recommended?
A: We recommend using AWS E2209 filler metal and preheat temperature of 150°C max. Detailed welding parameters are available upon request. -
Q: Do you provide third-party inspection certificates?
A: Yes, we can arrange inspection by SGS, BV, or other accredited agencies at your cost. Mill test certificates are included with each shipment. -
Q: What is the typical lead time?
A: For standard sizes (6mm x 2500mm x 1500mm), lead time is 15–20 working days after order confirmation. Custom sizes may take 25–30 days. -
Q: How do you ensure the plate is free from defects?
A: Each plate undergoes ultrasonic testing (UT) for internal soundness and visual inspection for surface quality. We also perform dimensional checks and mechanical testing per ASTM A240. -
Q: Is the plate suitable for offshore or marine environments?
A: Yes, Duplex 2205 offers excellent resistance to chloride-induced stress corrosion cracking, making it ideal for coastal and offshore applications such as chemical tanks on ships or platforms.
