Production method(Ⅱ)

Production method

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.
