AI Technical Summary
Insufficient interfacial bonding strength between stainless steel and carbon steel makes the composite plate prone to thermal stress during hot working and service, leading to a decrease in interfacial bonding strength or even delamination.
The process involves surface treatment of billets, assembly and sealing of billets, welding, vacuuming, heating, rolling, cooling, heat treatment and separation. By controlling the rolling reduction and heat treatment parameters, the bonding between the base material and the cladding material is optimized, resulting in an excellent composite plate preparation method.
Metallurgical bonding of the composite plate was achieved, improving the interfacial bonding strength and ensuring the performance of the composite plate under harsh working conditions, meeting the requirements of high strength, high toughness and low stress.
