Clad Steel Plate

Length: 2000mm - 16000mm
Cladding Material: Stainless Steel, Nickel Alloy, Titanium, Copper
Shanghai Metal Corporation is a leading Clad Steel Plate manufacturer and supplier.
Clad Steel Plate is a composite material manufactured by bonding a corrosion-resistant alloy layer (cladding) to a strong and cost-effective carbon or low-alloy steel base (backing). This product is engineered to solve the critical challenge of material selection in aggressive environments, where solid alloy plates are prohibitively expensive and carbon steel lacks the necessary corrosion resistance. It is widely used in the fabrication of pressure vessels, reactors, heat exchangers, and storage tanks for the chemical, petrochemical, and marine industries, providing an optimal balance of performance, safety, and economy.

1.Material Composition: Composed of a carbon steel backing (e.g., Q345R, ASTM A516) for structural strength and a corrosion-resistant cladding layer (e.g., 304/316L stainless steel, titanium, nickel alloy).
2. Bonding Method: Metallurgically bonded via hot rolling or explosive welding, ensuring the two layers act as one under stress.
3. Cladding Ratio: Cladding thickness typically accounts for 10%–20% of total plate thickness; customizable per application requirements.
4. Grade Combinations: Multiple combinations available, such as S30403/Q345R, N06625/SA516, Titanium Gr2/Q345R, etc.
5. Standards: Manufactured to ASTM A263/A264/A265 and ASME SA263/SA264/SA265 for pressure vessel applications.

1. Cost-Effective
Combines a thin layer of expensive alloy with affordable carbon steel, significantly reducing material costs versus solid alloy plates.
2. Corrosion Resistant
The cladding layer resists acids, alkalis, saltwater, and other corrosive media, ensuring long-term equipment integrity.
3. High Bond Strength
Metallurgical bonding delivers shear strength >200 MPa, preventing delamination under thermal cycling or high pressure.
4.Easy Fabrication
Can be cut, formed, and welded using standard workshop techniques; specialized procedures available for both layers.
5.Design Flexibility
Engineers can independently select optimal materials for cladding (corrosion resistance) and backing (mechanical strength).

Packaging of clad plate:
Standard Packaging
Each Clad Steel Plate is coated with anti-rust oil and wrapped in waterproof plastic film. Plates are stacked and secured with high-tensile steel straps onto fumigated wooden pallets or steel frames. For sea freight, the entire stack is enclosed in a reinforced wooden crate or covered with heavy-duty waterproof tarpaulin to prevent moisture and physical damage during transit.
Shipping
Due to the heavy weight and large dimensions of clad plates, we primarily support FCL (Full Container Load) sea freight and bulk vessel shipping. LCL (Less than Container Load) is available for smaller, cut-to-size orders. Trade terms include EXW, FOB, and CIF. Other terms may be available upon request. Shipping costs are calculated based on gross weight, cargo volume, destination port, and the chosen transportation method.
Lead Time
Standard Grades/Sizes: 25-35 working days
Customized Grades/Sizes: 40-60 working days
Q1: What is the difference between explosion-bonded and hot-rolled clad plates?
A: Explosion bonding uses high-energy shockwaves, making it suitable for thicker plates and wider material combinations (like Titanium/Steel). Hot-rolled cladding uses high heat and pressure, resulting in a smoother surface and lower cost for standard grades like stainless steel.
Q2: How do you weld clad steel plates?
A: Weld the backing steel first using standard carbon steel consumables. Then weld the cladding layer using matching alloy filler metals. Preventing carbon contamination in the cladding weld is critical.
Q3: What is the maximum thickness you can supply?
A: Up to 200mm or more, depending on the material combination. Very thick plates typically use explosion bonding.
Q4: Can you provide ultrasonic testing (UT) reports?
A: Yes. 100% Ultrasonic Testing is standard. We provide detailed UT reports per ASTM A578 or your specific requirements, mapping any unbonded areas.
Q5: What information do you need to provide a quotation?
A: Please provide: 1) Dimensions (cladding thickness, backing thickness, width, length); 2) Material grades for both layers (e.g., 316L/A516 Gr.60); 3) Required standard (e.g., ASTM A264); 4) Quantity; 5) Special testing or edge preparation needs.
Q6: What are the typical applications for Nickel Alloy clad plates?
A: They are used in severe corrosive environments, such as organic acid production (e.g., acetic acid), pharmaceutical intermediates, and Flue Gas Desulfurization (FGD) units requiring high resistance to chlorides and reducing acids.
