Analysis on yellow stain defect of SUS430 stainless steel and its process control
The yellow stain defect on the surface of SUS430 strip was analyzed and studied by the electron microscope and spectrum analyzer.The results showed that the insufficient ability of descaling in electrolytic area of production unit caused the residual iron scale adhering to strip surface,which was the main cause of the yellow stain defect.By modifying the Na2SO4 electrolysis process parameters,and improving the ability of degreasing and scrub,the yellow stain defect on the surface of SUS430 strip was eliminated.
