Effects of Heat Treatment on Microstructure and Properties of Stainless Clad Plate

Abstract:

The effect of heat treatment on microstructure and properties of Q345R/304 clad plate was studied. The microstructure of the base layer was analyzed by metallographic microscope and scanning electron microscope, and mechanical properties such as tensile, shear and impact were investigated after heat treatment. The chromium content in the compound interface was analyzed after heat treatment through spectrum analysis technology. The results show that heat treatment affects the mechanical properties and corrosion resistance of stainless clad plate significantly. After air cooling, the microstructure of the base layer consi+sts of ferrite and pearlite, the strength of clad plate is low, and the corrosion resistance is poor. After oil cooling to 450°Cand air cooling, the microstructure of the base layer consists of bainite, ferrite and a small amount of pearlite. The strength and plasticity of clad plate can meet the application requirements and the corrosion resistance is excellent as well.
