The base material of stainless steel clad plate can be various carbon ordinary steels and special steels such as Q235B, Q345R, 20R. The top layer material can be made of various grades of stainless steel such as 304, 316L, 1Cr13 and duplex stainless steel. Materials and thicknesses can be freely combined to meet the needs of different users. Stainless steel clad plate not only has the corrosion resistance of stainless steel, but also has the good mechanical strength and processing performance of steel carbon. It is a new industrial product. Stainless steel clad plates have been widely evaluated in the petroleum, chemical, and salt industries as a resource-saving product that reduces the consumption of precious metals and reduces project costs. It shows the perfect combination of appearance and high performance, and has good social benefits.
