How is stainless steel composite plate produced? There are two main methods for industrial production of stainless steel composite plates, explosive bonding and hot rolling bonding.

The production process of explosive composite plates is to overlap stainless steel plates on carbon steel substrates, and a certain distance is separated between the stainless steel plates and carbon steel substrates using a cushion. The stainless steel plate is paved with explosives, and the energy of the explosive explosion causes the stainless steel plate to impact the carbon steel substrate at high speed, generating high temperature and pressure, which enables solid-state welding of the interface between the two materials. Ideally, the shear strength per square millimetre of the interface can reach 400 MPa.

The hot rolled composite plate process is formed by rolling carbon steel substrates and stainless steel plates in a physically pure state under high vacuum conditions. During the rolling process, the two metals diffuse to achieve complete metallurgical bonding. Of course, in order to improve the wetting effect of the composite interface and enhance the bonding strength, a series of technical measures need to be taken in the physical and chemical treatment of the interface. The above two manufacturing methods for composite plates are in accordance with the national standard GB/T8165-2008. This standard is not equivalent to the Japanese JISG3601-1990 standard, and its main technical indicators are the same or higher than the Japanese standard.
