Carbon steel clad plate

Sheet Metal Cladding Process: A Comprehensive Overview

Carbon steel composite plate is composed of two or more layers of metal materials with different properties. The base material is carbon steel, and the covering material may be corrosion-resistant metals such as 304/316 stainless steel, titanium, copper or nickel depending on the purpose.

Common composite forms include:
Bimetallic Plate: such as stainless steel + carbon steel composite plate.
Multilayer Plate: three or more layers of composite metal structure, such as stainless steel + carbon steel + aluminum composite plate.
These composite plates have both structural bearing and surface performance functions, which are difficult to match with traditional single materials.

Technical standards for carbon steel composite plates

The technical requirements for carbon steel composite plates at home and abroad mainly refer to the following standards:
GB/T 8165 "Composite steel plates for pressure vessels"
American standards such as ASTM A264 / A265 / A263
ASME Boiler and Pressure Vessel Code (ASME Code)
These standards put forward strict control indicators for carbon steel composite plates in terms of composite quality, bonding strength, thickness deviation, etc.

Main production processes of carbon steel composite plates
1. Explosive composite method
Explosive composite is a technology that uses the shock wave released instantly by high-energy explosives to press carbon steel and composite metal at a very high speed. Its advantages include:
Can composite large areas and multiple metal combinations
High bonding strength, metallurgical bonding rate can reach more than 98%
Suitable for the combination of dissimilar metals, such as carbon steel + titanium, stainless steel + carbon steel, etc.
2. Hot rolling composite method
The hot rolling composite method is to heat the two metals to a plastic state and then combine them through multiple rolling. It is widely used in continuous mass production and is suitable for the combination of carbon steel with stainless steel, copper and other metals.
3. Explosive + rolling composite
In order to make up for the defects of a single method, some high-end applications use a composite process of first explosive composite and then hot rolling finishing, which has both bonding strength and surface flatness. It is one of the mainstream high-end preparation processes for carbon steel composite plates.

In actual projects, choose the appropriate type of carbon steel composite plate:

Use environment	Recommended composite metals	Recommended combination
Strong acid and alkali	Titanium, Hastelloy	Ti+Q235
Neutral corrosion	Stainless steel 304/316	SUS304+Q345R
High temperature environment	Nickel, molybdenum alloy	Ni+Q235B
Food grade hygiene	316L stainless steel	SUS316L+Q345R

These products are designed to withstand harsh environments, ensuring reliability and performance over long periods.

Technical advantages of carbon steel composite plates

1. Reduce costs
By using cheap carbon steel as the main material and only using precious metal composite layers on the surface, the overall material cost is greatly reduced, which is particularly suitable for the manufacture of large-area corrosion-resistant equipment.
2. Improve performance
The composite metal has good corrosion resistance, oxidation resistance, and high temperature resistance, which significantly extends the life of the equipment while maintaining high-strength structural performance.
3. Green and environmentally friendly
The use of carbon steel composite plates can reduce unnecessary metal waste, which is in line with the trend of energy conservation and carbon reduction; its recyclability is also conducive to the realization of circular manufacturing.
4. Strong process adaptability
Carbon steel composite plates can be processed by conventional cutting, welding, rolling and other processes, without the need for special equipment, which is conducive to rapid docking in downstream manufacturing links.​​​​​​​
Main application areas of carbon steel composite plates

1. Petrochemical equipment
The petrochemical industry widely uses carbon steel composite plates to manufacture pressure vessels, heat exchangers, storage tanks and other equipment. Carbon steel provides structural support for the main body, and stainless steel or titanium composite layers resist erosion by corrosive media.
Application scenarios:
High-pressure heat exchangers in oil refining
Inner walls of towers in fertilizer plants
Inner linings of acid and alkali storage tanks
2. Power and energy industry
Thermal power plants and nuclear power plants involve a large number of high-temperature and high-pressure devices, which have extremely high requirements for the pressure resistance and corrosion resistance of materials. Carbon steel composite plates can be used as an ideal choice for boiler tube plates, superheater components, etc.
3. Marine engineering
In seawater environment, single carbon steel is easily corroded, while pure titanium or stainless steel is expensive. Carbon steel composite plates achieve a balance between economy and corrosion resistance through titanium/stainless steel composite layers and are widely used in:
Seawater desalination equipment
Offshore platform pipelines
Hull corrosion-resistant coating materials
4. Food and medical equipment
In the process of food processing or pharmaceutical manufacturing, it is necessary to avoid pollution caused by metal ion precipitation. Stainless steel + carbon steel composite plates are often used to manufacture equipment such as reactors and mixing tanks.
