What is Duplex Stainless Steel Clad Plate?
Duplex Stainless Steel Clad Plate is a composite material consisting of a stainless steel layer bonded to a carbon steel or low-alloy steel base. This design combines the corrosion resistance of stainless steel with the mechanical strength and cost-effectiveness of carbon steel.
Advantages:
Excellent corrosion resistance, particularly in chloride and chemical environments
High tensile and yield strength
Cost-effective alternative to solid stainless steel plates
Suitable for welding, cutting, and forming
Chemical Composition & Mechanical Properties
| Material | C | Cr | Ni | Mo | N | Fe | Notes |
|---|---|---|---|---|---|---|---|
| Duplex Stainless Steel | ≤0.03 | 22 | 5.5 | 3 | 0.18 | Balance | 2205 / 2507 optional |
| Carbon Steel Base | ≤0.25 | ≤0.3 | ≤0.3 | ≤0.1 | – | Balance | ASTM A516 Gr70 / Q345B |
| Property | Stainless Steel Layer | Carbon Steel Base |
|---|---|---|
| Tensile Strength | 620–800 MPa | 400–550 MPa |
| Yield Strength | 450–550 MPa | 250–350 MPa |
| Elongation | 25–35% | 20–30% |
| Hardness | 280–320 HB | 150–180 HB |
Duplex Stainless Steel Clad Plate Applications
Duplex Stainless Steel Clad Plates are widely used in industries where both corrosion resistance and strength are critical:
Chemical and petrochemical tanks, reactors, and piping
Offshore and seawater equipment
Heat exchangers and pressure vessels
Industrial equipment handling acids, alkalis, and salt solutions
Why Choose Duplex Stainless Steel Clad Plate?
I believe many people have this question: why are there duplex stainless steel sheets and carbon steel plates/sheets on the market, and why manufacture duplex stainless steel composite sheets at all? Why not just choose duplex stainless steel sheets or carbon steel directly? Below are some points summarized by our company to answer your questions. If you have any further questions, please feel free to contact us.
Balanced Performance vs. Cost
Duplex stainless steel plate alone: Excellent corrosion resistance and mechanical strength, but very expensive for large structures due to full-thickness duplex material.
Carbon steel plate alone: Affordable and strong, but poor corrosion resistance, especially in chemical, marine, or offshore environments.
- Duplex stainless steel clad plate: Combines a carbon steel core with a duplex stainless steel surface, offering high corrosion resistance on the exposed surface while keeping the overall cost much lower than a full duplex plate.
Superior Corrosion Resistance Where It Matters
The duplex cladding layer is fully exposed to aggressive environments (chlorides, acids, seawater), preventing pitting and stress corrosion cracking.
The carbon steel core provides structural strength, supporting pressure vessels, tanks, or pipelines without the cost of a full stainless steel plate.
Mechanical Strength and Durability
Duplex stainless steel provides excellent tensile and yield strength, while the carbon steel core adds bulk structural support.
Full duplex stainless steel may be over-specified for mechanical support, while carbon steel alone would fail in corrosive conditions.
Customizable for Project Requirements
Thickness, width, length, and surface finish of the duplex layer can be tailored for specific industrial or marine applications.
Ensures the right balance of corrosion resistance, mechanical strength, and cost.
Summary:
Choosing Duplex Stainless Steel Clad Plate means you get the corrosion protection of duplex stainless steel where it counts, combined with the strength and affordability of carbon steel in the core. It is the most cost-effective and reliable solution for chemical plants, offshore structures, marine equipment, and other demanding environments.
