Standard Thickness Specifications and Ratios

Total Thickness Range Capabilities

The manufacturing capabilities for stainless clad plates encompass a comprehensive total thickness range of 6mm to 200mm, providing exceptional flexibility for diverse industrial applications. This extensive range allows engineers to select materials that precisely match their structural and performance requirements. The total thickness represents the combined measurement of both the base material and the stainless steel cladding layer, creating a composite structure that maximizes both strength and corrosion resistance. Manufacturing processes such as explosion bonding and hot rolling enable the production of these varied thickness combinations while maintaining consistent metallurgical bonding throughout the entire plate structure. The ability to produce stainless clad plates within this broad thickness spectrum ensures that applications ranging from thin-walled chemical reactors to heavy-duty pressure vessels can be adequately served. Quality control measures during production guarantee that each thickness combination meets stringent international standards including ASTM A264, ASME SA-264, and GB/T 8165 specifications, ensuring reliable performance across all available thickness ranges.

Clad Layer Thickness Variations

The stainless steel cladding layer represents the protective barrier that provides corrosion resistance and enhanced surface properties to the composite material. Available in thicknesses ranging from 1mm to 20mm, the clad layer can be customized to match specific environmental challenges and performance requirements. Thinner clad layers of 1mm to 5mm are typically employed in applications where moderate corrosion protection is required, such as architectural cladding or food processing equipment. Medium thickness clad layers ranging from 5mm to 12mm offer enhanced protection for chemical processing equipment, marine structures, and offshore platforms where aggressive environments demand superior corrosion resistance. Thick clad layers exceeding 12mm are reserved for the most demanding applications including high-pressure vessels, extreme temperature environments, and critical infrastructure components where long-term reliability is paramount. The stainless clad plate manufacturing process ensures that regardless of the chosen clad layer thickness, the metallurgical bond between the stainless steel and base material maintains exceptional strength characteristics, with bonding strength typically exceeding 140 MPa and shear strength surpassing 105 MPa.

Base Layer Thickness Customization

The base layer in stainless clad plates provides the primary structural strength and load-bearing capacity, with available thicknesses ranging from 5mm to 180mm to accommodate various mechanical requirements. This substantial range enables the selection of appropriate base layer thicknesses for applications spanning from lightweight architectural elements to heavy-duty industrial equipment. Common base materials include carbon steel grades such as Q235B, Q345B, and A516 Gr.70, each offering distinct mechanical properties suitable for different operational environments. The base layer thickness selection depends on factors including required load capacity, operating pressure, temperature conditions, and overall structural requirements. Thinner base layers of 5mm to 25mm are suitable for applications requiring flexibility and weight reduction, while maintaining adequate strength for moderate service conditions. Medium thickness base layers ranging from 25mm to 80mm provide enhanced structural integrity for pressure vessels, heat exchangers, and process equipment operating under moderate to high stress conditions. Thick base layers exceeding 80mm are engineered for heavy-duty applications including large-scale pressure vessels, structural components, and critical infrastructure where maximum load-bearing capacity and structural stability are essential for safe operation.

Manufacturing Process Impact on Thickness Combinations

Explosion Bonding Thickness Capabilities

Explosion bonding represents a highly effective manufacturing process for creating stainless clad plates with specific thickness combinations, particularly excelling in applications requiring maximum bonding strength and reliability. This high-energy process utilizes controlled explosions to achieve metallurgical bonding between the stainless steel cladding and base material, enabling the production of thickness combinations that would be challenging to achieve through conventional methods. The explosion bonding process is particularly well-suited for producing stainless clad plates with total thicknesses ranging from 10mm to 150mm, where the explosive energy can effectively penetrate and bond the entire thickness of the composite structure. The process excels in creating combinations where the base layer thickness significantly exceeds the clad layer thickness, such as configurations featuring 2mm stainless steel cladding bonded to 18mm carbon steel base material. The intense pressure and temperature generated during the explosion bonding process create a wavy interface between the materials, resulting in exceptional bonding strength that often exceeds the strength of the individual base materials. This manufacturing method is particularly valuable for producing stainless clad plates intended for high-stress applications including pressure vessels, offshore platforms, and critical infrastructure components where bonding integrity is paramount.

Hot Rolling Process Applications

Hot rolling represents a versatile manufacturing process for producing stainless clad plates with specific thickness combinations, particularly effective for creating uniform composite structures with consistent bonding characteristics. This process involves passing the assembled base material and stainless steel cladding through heated rollers under extreme pressure, creating a strong metallurgical bond while achieving precise thickness control. The hot rolling process is exceptionally well-suited for producing stainless clad plates with total thicknesses ranging from 6mm to 80mm, where the rolling forces can effectively compress and bond the materials throughout their entire thickness. This manufacturing method excels in creating thickness combinations with relatively thin clad layers, typically ranging from 1mm to 10mm, bonded to base materials of varying thicknesses. The controlled temperature and pressure application during hot rolling ensures uniform bonding strength across the entire plate surface, resulting in consistent mechanical properties and corrosion resistance. The process is particularly valuable for producing stainless clad plates intended for applications requiring high surface quality and dimensional accuracy, such as chemical processing equipment, food processing machinery, and architectural applications where appearance and performance are equally important.

Combined Manufacturing Techniques

Advanced manufacturing approaches often utilize combined techniques, such as explosion bonding followed by hot rolling, to achieve optimal thickness combinations and superior material properties in stainless clad plates. This hybrid approach leverages the benefits of both processes, using explosion bonding to create the initial metallurgical bond and hot rolling to refine the final thickness, improve surface quality, and enhance overall mechanical properties. The combined process is particularly effective for producing stainless clad plates with complex thickness combinations, such as configurations requiring multiple clad layers or varying thickness profiles across the plate surface. This manufacturing approach enables the production of stainless clad plates with total thicknesses ranging from 8mm to 200mm, with exceptional control over both clad layer and base layer thickness distributions. The initial explosion bonding creates a strong foundational bond, while subsequent hot rolling operations refine the final dimensions and improve the interface characteristics between the materials. This combined manufacturing technique is especially valuable for producing stainless clad plates intended for critical applications where both exceptional bonding strength and precise dimensional control are required, such as aerospace components, nuclear industry applications, and high-performance chemical processing equipment.
