Stainless Steel Clad/ Composite Plate is composed of base carbon steel and cladding stainless steel.Its main feature is a strong metallurgical bond between carbon steel and stainless steel.Production ways can be hot pressing, cold bending, cutting, welding and other processing, with good technical performance.
Introduction for Stainless Clad Plate:
Stainless Steel Clad/ Composite Plate’s base material can use A36,SS400,A516Gr70,Q235B, Q345R, 20R and other ordinary carbon steel and special steel.The cladding material can be made of 304, 316L, 1Cr13 and duplex stainless steel.materials and thickness can be freely combined to meet the needs of different users.Stainless Steel Clad/ Composite Plate not only has the corrosion resistance of stainless steel, but also has the good mechanical strength and processing performance of carbon steel, is a new industrial product.Stainless Steel Clad/ Composite Plate has been widely used in petroleum, chemical, salt industry, water conservancy and electric power, and other industries.As a kind of resource-saving product, Stainless Steel Clad/ Composite Plate can reduce the consumption of precious metal and greatly reduce the project cost.Achieve the perfect combination of low cost and high performance, with good social benefits.
Production methods for Stainless Clad Plate
How is Stainless Steel Clad/ Composite Plate produced?There are two main methods for the industrial production of Stainless Steel Clad/ Composite Plate: explosive composite and hot rolled composite.
The production process of the explosive composite plate is to overlap the stainless steel plate on the carbon steel substrate, the stainless steel plate and carbon steel substrate with a certain distance between the pad.The explosive is laid on the stainless steel plate. The explosive explosion energy causes the stainless steel plate to hit the carbon steel substrate at high speed, generating high temperature and high pressure to achieve solid phase welding at the interface of the two materials.Ideally, the shear strength per square millimeter of the interface can reach 400 MPa.
Hot rolled composite plate technology is based on carbon steel substrate and stainless steel plate in the physical purity state, rolled under high vacuum conditions.During the rolling process, the diffusion of the two metals achieves a complete metallurgical bonding.Of course, in order to improve the wetting effect and bonding strength of the composite interface, a series of technical measures should be taken in physical and chemical treatment of the interface.The above two composite plate manufacturing methods are implemented in accordance with GB/ t8165-2008 national standards.This standard is not equivalent to jisg 3601-1990, and the main technical indicators are the same or higher than jisg.
Process Characteristics for Stainless Clad Plate
Characteristics of Explosive Compounding Process
1, Because the explosion composite is cold processing, so it can produce in addition to Stainless Steel Clad/ Composite Plate many kinds of metal composite plate, such as titanium, copper, aluminum and so on.
2, Explosive composite can produce Stainless Steel Clad/ Composite Plate total thickness can reach several hundred mm thick Stainless Steel Clad/ Composite Plate, such as some large base and tube plate.However, it is not suitable for the production of thinner composite steel plates with a total thickness of less than 10 mm.
3. The energy production of explosive combined with explosives will cause vibration, noise and smoke pollution to the environment.But the equipment investment is small, the size of domestic explosive production plant has hundreds.Due to the limitation of weather and other technological conditions, the efficiency of explosive compound production is low.
Characteristics of Hot Rolling Composite Process
1. Large medium plate mill and hot tandem mill are used for production, so the production efficiency is high and the supply speed is fast.Product size, thickness of the free combination.Stainless steel cladding thickness of more than 0.5mm can be produced.But the investment is large, so there are fewer manufacturers.
2. Due to the limitation of the compression ratio of rolled steel, the hot-rolling production is not able to produce composite steel plates with thickness of more than 50mm, nor is it convenient to produce composite plates of various small batches, circles and other special shapes.Advantages of hot rolled composite plate 6, 8, 10 mm thin specification composite plate.Under the condition of hot continuous rolling, it can produce composite coil, reduce the production cost and meet more users' demands.
3. Under the current technical conditions, the hot-rolling process cannot directly produce titanium, copper, aluminum and other non-ferrous metal composite plates.
In a word, two different production processes have their own characteristics, exist and develop at the same time, to meet the different needs of different users.The explosive rolling method is a combination of the two processes mentioned above.
Cold-rolled Stainless Steel Clad/ Composite Plate
After annealing, pickling, cold rolling, intermediate annealing, pickling (or bright annealing) tension rectification and other production processes on the basis of hot-bonded Stainless Steel Clad/ Composite Plate, the stainless steel composite coil (plate) suitable for civil use has been produced.Thinnest to 0.6mm.
Stainless Steel Clad/ Composite Plate has all kinds of carbon steel and stainless steel characteristics, with its excellent performance and price ratio for users welcome, has a broad market prospect.But interestingly, after more than half a century of development, starting in the 1950s, many people still don't know about it.More people don't use it.It should be said that the market of Stainless Steel Clad/ Composite Plate is gradually entering the maturity period, but there is still a lot of development work to be done.Scientific and technological workers will never stop their exploration and efforts to build a resource-conserving society.
Market Application for Stainless Clad Plate
Nowadays, coal coking, coal gasification, ammonia synthesis and chemical fertilizer have become the major coal-chemical industries in China, and have been sustained and rapidly developed.Domestic oil consumption growth and oil supply and demand of the contradiction, and methanol production of olefin, coal-to-oil and other coal-to-chemical industrial technology introduction, development of industrialization construction speed, engaged in coking products production enterprises are springing up like bamboo shoots after a bamboo shoots after a bamboo shoots after a bamboo shoots after a bamboo shoots after a bamboo shoots after a bamboo shoots after a bamboo shoots after a bamboo shoots after a bamboo shoots after a bamboo shoots after a bamboo shoots after a bamboo shoots after a bamboo shoots after a bamboo shoots after a bamboo shoots after a bamboo plant.Such as wuxi gangze metal materials co., LTD.
For the coal coking industry, due to the pipeline, equipment and other long time in the high temperature, corrosive environment, equipment corrosion is serious, the service life of equipment will be greatly reduced.Therefore, to improve the corrosion resistance of equipment, extend the service life of equipment, reduce the cost of production, is an important means to improve the competitiveness of enterprises.
Stainless Steel Clad/ Composite Plate is a pure stainless steel outer layer, the inner layer is carbon steel metal composite material, this pure stainless steel and carbon steel composite metal composite material is Stainless Steel Clad/ Composite Plate, the emergence of Stainless Steel Clad/ Composite Plate, for the coking equipment manufacturing, upgrading and transformation of the material support.
1, The use of Stainless Steel Clad/ Composite Plate instead of the original pure stainless steel plate, can reduce the cost of equipment, but the use of equipment is not affected.Stainless Steel Clad/ Composite Plate can be used for desulfurization tower, steam ammonia tower, dephenyl tower, low cost, corrosion resistance;Take the debenzol tower as an example, the use of Stainless Steel Clad/ Composite Plate instead of pure stainless steel plate, the cost can be reduced by more than 30%.
2, The Stainless Steel Clad/ Composite Plate has retained the pure stainless steel corrosion resistance, wear resistance, diamagnetic performance and beautiful appearance of the characteristics, and also has the carbon steel good weldability, formability, tensile, thermal conductivity.It can be widely used in coking equipment to improve the corrosion resistance of coking equipment and prolong the service life of equipment.
