This composite construction provides the corrosion protection of Alloy 625 while reducing the quantity of expensive nickel alloy required compared with solid Alloy 625 plate.
We support project-specific material selection, explosion-bonded and roll-bonded plate procurement, customized dimensions, inspection planning, and export delivery for equipment manufacturers, EPC contractors, fabricators, and industrial material distributors.
What Is Alloy 625 Clad Plate?
Alloy 625 clad plate is a metallurgically bonded composite metal plate consisting of a corrosion-resistant Alloy 625 layer and a structural steel backing plate.
The nickel alloy cladding forms the process-contact surface, while the backing steel provides much of the structural strength and thickness required for the equipment.
Unlike surface coatings or electroplating, metallurgically bonded clad plate incorporates a relatively thick, integral metallic layer designed to remain attached during qualified fabrication and service.
A typical Alloy 625 clad steel plate contains three functional components.
1. Alloy 625 Corrosion-Resistant Layer
The exposed Alloy 625 surface provides resistance to various aggressive environments, including chloride-containing process fluids, seawater, and selected chemical processing media.
Its chromium, molybdenum, and niobium content contributes to corrosion resistance, mechanical strength, and material stability.
2. Metallurgical Bonding Interface
The bonding interface connects the nickel alloy cladding to the structural backing steel.
Bond integrity is particularly important during plate forming, welding, thermal processing, and equipment operation.
Appropriate bond testing and ultrasonic examination help evaluate the integrity of this interface.
3. Structural Steel Base Plate
The carbon steel or low-alloy steel substrate supplies structural thickness and mechanical support.
For pressure-retaining equipment, the contribution of the backing steel and cladding to design strength must be evaluated according to the applicable construction code.
This combination enables equipment designers to use an expensive corrosion-resistant alloy where it is needed while selecting a more economical material for the structural backing.

The chemical composition of the Alloy 625 cladding material should be verified through the corresponding material test certificate.
The backing steel must independently meet the chemical composition requirements of its specified material grade.
For critical projects, positive material identification may be included in the inspection plan to verify the alloy composition.
Mechanical Properties of Alloy 625 Clad Plate
The mechanical properties of clad plate depend on the backing steel, cladding thickness, bonding process, heat treatment, and finished plate condition.
It is important to distinguish between the properties of solid Alloy 625 and those of the completed composite plate.
Reference Mechanical Properties of Alloy 625 Plate
| Property | Grade 1 – Annealed | Grade 2 – Solution Annealed |
|---|---|---|
| Tensile Strength | 760 MPa minimum | 690 MPa minimum |
| 0.2% Yield Strength | 380 MPa minimum | 275 MPa minimum |
| Elongation | 30% minimum | 30% minimum |
| Material | UNS N06625 | UNS N06625 |
| Reference Product Standard | ASTM B443 | ASTM B443 |
These values are indicative minimum requirements for certain hot-rolled Alloy 625 plate conditions under ASTM B443. Requirements vary with product form, thickness, condition, and the applicable standard edition. They must not be treated as guaranteed properties of the finished clad plate.
Mechanical Performance of the Composite Plate
For Alloy 625 clad steel plate, the following characteristics must be evaluated separately:
Base Metal Strength: Tensile strength, yield strength, and impact toughness according to the specified backing steel grade.
Cladding Properties: Chemical composition, thickness, and material condition according to the applicable Alloy 625 specification.
Bond Integrity: Mechanical bonding performance according to the applicable clad plate specification and purchase requirements.
Composite Plate Properties: Finished plate mechanical properties as required by the relevant product specification and equipment design code.
For pressure vessel applications, the design engineer must determine whether cladding is included in the strength calculation under the governing code.
Physical Properties of Alloy 625
The following values describe Alloy 625 itself rather than the steel-backed composite plate.
| Property | Approximate Value |
|---|---|
| Density | 8.44 g/cm³ |
| Elastic Modulus at Room Temperature | 208 GPa |
| Melting Range | 1290–1350°C |
| Magnetic Behavior | Essentially Nonmagnetic |
| Strengthening Mechanism | Solid-Solution Strengthening |
| Corrosion Resistance | High Resistance to Various Chloride-Containing Environments |
Thermal expansion, thermal conductivity, and other physical properties vary with temperature.
For clad plate fabrication involving elevated temperatures, the different thermal expansion characteristics of Alloy 625 and the backing steel must also be considered.
Manufacturing Methods: Explosion Bonding vs. Roll Bonding
The bonding method is a critical factor in the production of high-quality nickel alloy clad steel plate.
Alloy 625 clad plate may be manufactured using qualified explosion-bonding or hot-roll-bonding processes, depending on the material combination, plate dimensions, and technical requirements.
Explosion Bonded Alloy 625 Clad Plate
Explosion bonding uses controlled high-energy impact to join the cladding metal and backing steel through a solid-state bonding process.
The process creates a metallurgical interface without requiring the bulk materials to melt.
Explosion bonding may be suitable for:
Heavy-gauge composite plates
Selected dissimilar-metal combinations
Custom corrosion-resistant plate structures
Pressure vessel components
Special engineering projects
Engineering Considerations
The bonding interface, residual stresses, plate flatness, and any subsequent heat treatment requirements must be evaluated according to the approved manufacturing procedure.
Ultrasonic examination and mechanical bond testing are important elements of quality verification.
Hot Roll Bonded Alloy 625 Clad Plate
Hot roll bonding joins the cladding and backing materials through controlled high-temperature deformation.
Under suitable processing conditions, the metals develop a metallurgical bond through the rolling process.
Hot roll bonding may be selected for:
Industrial plate production
Repetitive plate specifications
Selected large-format clad plates
Chemical processing equipment
Pressure vessel plate fabrication
Engineering Considerations
Bonding temperature, reduction ratio, surface preparation, and heat treatment must be controlled to achieve the required mechanical properties and bond quality.
Manufacturing Process Comparison
| Parameter | Explosion Bonding | Hot Roll Bonding |
|---|---|---|
| Bonding Principle | High-Energy Impact | High-Temperature Rolling |
| Bonding Type | Metallurgical | Metallurgical |
| Typical Production Approach | Project-Specific | Mill-Based Production |
| Heavy Plate Applications | Often Suitable | Depends on Rolling Capability |
| Material Combination Flexibility | Broad for Qualified Combinations | Process Dependent |
| Bond Interface | Requires Qualification and Inspection | Requires Qualification and Inspection |
| Typical Quality Controls | UT, Mechanical Tests, Dimensional Inspection | UT, Mechanical Tests, Dimensional Inspection |
| Selection Basis | Geometry, Materials, Specification | Geometry, Materials, Specification |
Neither process is universally superior.
The appropriate manufacturing route depends on the required plate geometry, cladding ratio, service conditions, qualification requirements, and project economics.
Important: Weld overlay cladding is another method of applying Alloy 625 to steel, but it is a different manufacturing process from supplying an integrally bonded composite clad plate. The two product types should not be treated as automatically interchangeable.
Corrosion Resistance of Alloy 625 Clad Steel Plate
Alloy 625 is widely used in corrosive industrial environments because of its nickel-chromium-molybdenum-based composition.
The alloy provides a combination of general corrosion resistance, localized corrosion resistance, and mechanical strength.
Chloride-Induced Pitting Resistance
Molybdenum and chromium contribute to Alloy 625's resistance to localized corrosion in many chloride-containing environments.
This characteristic is particularly valuable in seawater processing equipment, offshore systems, and selected chemical manufacturing applications.
Crevice Corrosion Resistance
Alloy 625 offers strong resistance to crevice corrosion compared with many conventional stainless steels.
However, crevice geometry, chloride concentration, temperature, deposits, and oxidizing conditions can significantly influence performance.
Stress Corrosion Cracking Resistance
The nickel-rich composition provides good resistance to chloride-induced stress corrosion cracking in many environments where austenitic stainless steels may be vulnerable.
Material suitability must still be verified for the actual process fluid and operating conditions.
Chemical Processing Resistance
Alloy 625 may be selected for equipment exposed to various acidic, alkaline, and mixed chemical environments.
Corrosion performance depends on the exact chemical concentration, contamination level, temperature, flow conditions, and operating cycle.
Material Selection Note: Alloy 625 should not be described as universally resistant to all acids or chloride solutions. Chemical compatibility must be assessed using relevant corrosion data and project operating conditions.
Alloy 625 Clad Plate Applications
Chemical and Petrochemical Processing
Alloy 625 clad steel plate is suitable for consideration in chemical processing equipment requiring a corrosion-resistant process-contact surface over a structural steel backing.
Potential applications include:
Chemical reactors

Gas processing vessels
Separation equipment
Offshore process systems
Corrosion-resistant pressure equipment
Selected sour-service components
For sour-service applications, the material system, welding procedures, and relevant requirements of ISO 15156 / NACE MR0175 must be evaluated where applicable.
Marine and Offshore Engineering
Alloy 625 offers corrosion resistance in many seawater and chloride-rich environments.
Potential applications include marine processing equipment, offshore vessels, seawater handling systems, and corrosion-resistant equipment components.
Desalination and Water Treatment
Alloy 625 clad construction may be considered for selected equipment used in desalination and seawater treatment facilities.
Applications include high-corrosion-risk process vessels, specialized seawater equipment, and associated industrial components.
Heat Exchangers and Pressure Vessels
Clad steel plates are particularly useful where equipment requires both corrosion-resistant surfaces and substantial structural wall thickness.
The backing steel provides structural support, while the nickel alloy layer protects the process-contact surface.
Tube sheets, shell sections, vessel heads, and other fabricated components may require additional bonding, machining, welding, or inspection controls.
Flue Gas and Industrial Chemical Treatment
Alloy 625 clad plate may be considered for selected flue gas treatment and chemical processing systems exposed to aggressive condensates or chloride-containing conditions.
Final material selection should be supported by process-specific corrosion evaluation.
How to Select the Correct Alloy 625 Clad Plate
Choosing the correct clad plate requires more than specifying the alloy grade and overall plate thickness.
The following factors should be reviewed before procurement.
1. Select the Base Metal
ASTM A516 Grade 70 is a commonly considered backing material for pressure vessel applications.
Other carbon steel and low-alloy grades may be selected according to the required mechanical strength, operating temperature, impact toughness, and fabrication requirements.
A stainless steel substrate may also be considered for a special engineered composite, but it should not automatically be specified as complying with ASTM A265, which covers carbon steel and low-alloy steel backing materials.
2. Determine the Required Cladding Thickness
The Alloy 625 layer must provide sufficient corrosion-resistant thickness after any required forming, machining, fabrication, and welding operations.
The specified thickness should account for the engineering design, manufacturing tolerances, and any applicable corrosion allowance.
3. Confirm Service Conditions
Important operating parameters include:
Design temperature
Design pressure
Process fluid composition
Chloride concentration
pH and acid concentration
Corrosion allowance
Thermal cycling conditions
Expected service life
4. Select the Bonding Process
Explosion bonding and hot roll bonding offer different manufacturing characteristics.
The selection should consider material compatibility, plate dimensions, mechanical property requirements, and inspection standards.
5. Confirm Inspection and Certification Requirements
For pressure vessel and critical industrial applications, the purchase specification should clearly state the bond inspection method, acceptance criteria, mechanical tests, traceability requirements, and inspection certificate type.
Fabrication, Welding and Heat Treatment
Alloy 625 clad plate can be fabricated into equipment components using qualified cutting, forming, machining, and welding procedures.
However, the dissimilar-metal structure requires additional engineering controls compared with conventional homogeneous steel plate.
Cutting and Edge Preparation
Mechanical cutting, thermal cutting, and other suitable methods may be used depending on plate thickness and fabrication requirements.
Edge preparation should prevent excessive contamination or damage to the Alloy 625 cladding surface.
For welded joints, the required groove geometry and cladding restoration procedure should be established before fabrication.
Forming and Bending
Forming procedures must account for the mechanical characteristics of the backing steel, cladding layer, and metallurgical bonding interface.
Minimum forming radius, forming temperature, and intermediate or final heat treatment requirements should be evaluated according to the material combination.
Additional bond-integrity inspection may be required after severe forming operations.
Welding
Welding must use procedures qualified for the selected backing steel and Alloy 625 cladding system.
Depending on the welding process, suitable Alloy 625 filler metals may include:
AWS A5.14 ERNiCrMo-3
AWS A5.11 ENiCrMo-3
Final filler metal selection depends on the joint design, welding process, corrosion requirements, and applicable fabrication code.
Special attention should be given to:
Welding procedure qualification
Base metal and cladding weld sequence
Dilution control
Cladding restoration at joints
Surface contamination prevention
Weld inspection requirements
Post-Weld Heat Treatment
Any post-weld heat treatment must be evaluated for compatibility with the backing steel, Alloy 625 cladding, and bonding interface.
The heat treatment required for the backing steel may influence the microstructure and corrosion performance of the nickel alloy layer.
Therefore, the complete thermal cycle should be reviewed and approved before fabrication.
Inspection & Quality Assurance
For industrial Alloy 625 clad plate, quality assurance must address both the individual metals and the integrity of the composite structure.
Inspection and testing requirements are determined by the applicable product standard, customer specification, and approved inspection and test plan (ITP).
