There are two main methods for industrial production of Stainless Steel Composite Panel https://www.alubang.net/product/stainless-steel-composite-panel.html
, explosive compounding and hot rolling compounding.
The production process of explosive composite panel is to overlap stainless steel panel on carbon steel substrate, and space a certain distance between stainless steel panel and carbon steel substrate with cushion. Explosives are spread on the stainless steel panel, and the energy of explosive explosion makes the stainless steel panel hit the carbon steel substrate at high speed, resulting in high temperature and high pressure, which makes the interface between the two materials realize solid phase welding. Ideally, the shear strength per square millimeter of the interface can reach 400 MPa.
Hot-rolled composite panel technology is made by rolling carbon steel substrate and stainless steel panel in physically pure state under high vacuum condition. In the rolling process, the two metals diffuse to realize 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 the physical and chemical treatment of the interface.
