Common thicknesses:
2205 Duplex Stainless Steel: 6–20mm (used in seawater equipment, pipelines, and pressure vessels)
904L Super Stainless Steel: 3–16mm (used in chemical equipment, desulfurization, and pickling equipment)
Mechanical properties
Core Performance and Advantages
2205 Duplex Stainless Steel
Extremely high strength, approximately twice that of 304/316, allowing for thinner applications and reduced structural weight.
Extremely strong resistance to stress corrosion cracking (SCC), solving the cracking problem of 304/316 in chloride ion environments.
Excellent resistance to pitting and crevice corrosion, suitable for seawater, chlorinated water, oil and gas, and chemical media.
Medium to high temperature resistance, fatigue resistant, suitable for high-pressure, high-load equipment.
904L Super Austenitic Steel
Extremely strong and comprehensive corrosion resistance, resistant to sulfuric acid, phosphoric acid, organic acids, seawater, salt spray, pitting, and crevice corrosion.
Low carbon, high nickel, and high molybdenum content; no intergranular corrosion after welding, suitable for chemical equipment, desulfurization, and pickling equipment.
Good toughness and formability, suitable for deep drawing, pressure vessels, and heat exchangers. Service life far exceeds 316L in highly corrosive environments.
Application Areas:
2205: Seawater desalination equipment, marine engineering, oil and gas pipelines, water treatment equipment, chemical heat exchangers, storage tanks, towers, pulp and paper making, desulfurization equipment, high-pressure pipelines, high-stress structural components
904L: Sulfuric acid, phosphoric acid, organic acid equipment, flue gas desulfurization (FGD), pickling equipment, chemical reactors, high-chlorine, high-pollution corrosive conditions, high-end seawater, nuclear power, precision chemical equipment
Export Packaging:
Inner layer: Rust-proof paper + VCI rust-proof film
Outer layer: IPPC fumigated wooden pallet + steel strap fastening
Identification: Material, specifications, batch number, gross and net weight

Payment Methods
Flexible payment terms available: T/T and L/C. For new clients, 30% advance payment for production, balance against copy of B/L. L/C is acceptable for large & regular orders to secure both parties.
Warehousing Management
Before each batch of steel leaves the factory, a complete process inspection is strictly carried out. From chemical composition, mechanical properties to dimensional tolerance and surface quality, each item is carefully checked to ensure compliance with national standards and export regulations. At the same time, the quantity, packaging and rust prevention treatment are also verified. An original factory warranty certificate is attached, guaranteeing the quality. Before shipment, inspection photos are provided. Any non-compliant items will not be released, and the quality is fully controllable throughout the process. This ensures your overseas purchasing is safe and worry-free.
All items are visually inspected before delivery. No cracks, deformation, rust, scratches or cutting marks are allowed; edges must be smooth. Only visually sound products will be shipped.
Thickness, width, length, wall thickness, outer diameter have been measured. Straightness, curvature, torsion, diagonal tolerance all meet the corresponding tolerance requirements.
Quality inspection includes: mechanical property tests (yield strength, tensile strength), elongation rate, impact energy, hardness testing, chemical composition testing, process performance testing, etc.
Inspection according to packaging requirements: secure binding, moisture-proof film, rust-proof paper, export fumigation/fumigation-free wooden crates, shipping marks, gross weight, net weight, etc.
We will provide full reception services to support the customers' on-site inspection of the goods.
Warehousing Management
A ten-thousand-ton standardized warehouse with grid-based zoning and system positioning enables rapid material retrieval and reduces the time spent searching for materials.
Inbound inspection: Verify the physical items against the inbound form, inspect the appearance, dimensions, and labels. Once confirmed to be correct, the materials are entered into the ERP system and processed for storage.
Logistics and Global Delivery: Self-operated fleet + contracted logistics partners; expedited service available for urgent orders.
International Shipping: Supports FOB, CIF, DDP, and other trade terms, covering 100+ countries and regions.
Process: Booking → Trucking → Customs Declaration → Loading onto Ship/Aircraft → Bill of Lading Issuance → Document Delivery → Destination Port Customs Clearance (Optional) → Last-Mile Delivery.
Provides door-to-door one-stop logistics with full tracking to ensure safe and timely arrival of goods.
After-Sales Service and Traceability: Delivery receipts, logistics information, and quality inspection documents are sent to customers within 24 hours of shipment.
Established a full product lifecycle traceability system, allowing tracking of production, quality inspection, warehousing, and transportation records.
Follow-up inspection within 72 hours of arrival; rapid response and handling of quality issues; assistance in resolving customs clearance issues for foreign trade orders.
